Chapter 1: Fuyuki City

M78- Land of Light

In a white room, surrounded by metal wall without any windows beside 4 greek-like pillars at each corner. At the center of the room, a red-silver giant standing in front of a man.

The 170 feet tall giant has a silver head with 2 bullhorns at both sides of his head and a large reverse fin on top of his head with a green gem on his forehead. His eyes shaped like a hexagon-rectangle hybrid with a small black pupil at the center of his eyes. His mouth looks like it couldn't move and his body has a crimson color. There is another blue gem at the center of his chest, protected by a layer of silver torso armor that decorate with small round jewels at a line pattern. Another feature on his body is a vertical gray stripe that split into 2 smaller stripes when it nearly reaches the giant crotch. On his right hand is a silver bracelet that adorns a yellow rhombus.

While the 6 foot 2 man seems over thirty with a short haircut. He has a fedora and a brown leather jacket over his shoulder. Beneath is a blue shirt with gray jeans. Hang on his belt is 2 strange devices. The device on his left side is a strange device with a holder at the bottom and a big blue ring at the top. There are 2 small wings at the opposite sides of the ring. The equipment on his right side is a silver card container with the blue ring at the center.

The red and silver giant speak to the man with a mid-40s years old man voice.

"Gai, there is another threat appear on Earth."

"Already? I don't think I need to intervene anyway, the kid can handle whatever throw at him. Have some faith in him." the man said nonchalantly.

"No, I never doubted Geed ability, he is the "son" of Belial after all. But this threat is from another Earth."

"Another Earth?" the man scratches his chin, this is not a big surprise for him because he has met few giants came from another realm as well.

"Yes, humanity is facing a large threat that could lead to their extinction in that Earth."

"Are we talking about another invasion of Galactron?"

"No, this is something else. Someone has damaged the timeline in human history."

"Human timeline? Do you mean time travel?" the man cocked an eyebrow

"Yes, it seems so. And from what I see, the culprit is another human."

"And you want me to stop that mysterious person?" the man put his hands on his hip.

"No, I knew that humanity will send its own guardians to stop that culprit. However, what I worry is the threat behind that criminal."

"What do you mean?"

"I just discovered that there is a great danger, an unseen darkness, another Ultras."

"Another Ultras that carry darkness?" the man put his hand under his chin, his face turns grim.

"Yes, it seems Belial was not the only Dark Ultras after all. I can feel this darkness grow powerful by day. It's feeding on humanity lifeforce. We cannot let humanity pay for our mistake." the red giant cross his arm.

"So why do you choose me? Why not Zero?" the man point to himself.

"Zero is powerful but inexperience, this is not some normal Kaiju we talking about here. This is a powerful unknown force that will swallow the universe. You have the experience and knowledge about Earth more than any Ultras, even Tiga and Gaia."

"So, return to Earth one more time, heh? I could work with that." the man smirk.

"Wait, before you go, I want to warn you something."

"What it is?"

"This universe is vastly different than our, you will need a new body, a human body. This is a requirement to pass the border between this universe and our."

"Wait! What?! Are you serious?!" the man exclaim

"Do not worry, the light will soon return with you." the silver giant raises his left palm up, showing the sign for the man to calm down.

"What do you mean?"

"Your power will return to you when the time comes and when that happens, the aspect of Ultras shall be with you. But before that time come, you will be like every human. But remember … if your death, your true body will come back to this world again and the bridge between our universe and there will be cut off, forever."

There were a few minutes of silent between both of them.

"I know this is a difficult task to ask but -"

"Is alright. This is a good chance for me to live a new life, even for a short time." the man shrugged.

"You are a strange Ultras, Gai." the giant chuckled and surprised by the man answer.

" Very well, is time for you to go. This gate will be your portal to that world." the red giant point to a door behind him.

The mysterious man walks to the large church like-door at the end of the room before giving a final glance at the giant he just talked with "See you later, Ultraman Taro."

The red silver giant nodded at the man before raising his right arm high, his voice echo through the room.

"Good luck, Gai Kurenai. Everyone in that world is waiting for you, dark night will illuminate you, the warrior of light."

Antarctica- Chaldea- the Hallway

Chaldea Security Organization, a secret agency founded with the purpose of preventing the "certain extinction" of the human race. Their purpose is noble and admirable. The facility is built 6000 meters above sea level. Apart from any civilization, protected by a magnetic field, with maximum security. Today is an important day, candidates, magus from all over the world are showing up here, from professional to amateur. Each has different tasks but will serve in a common purpose. Some could say that humanity depends on their shoulder.

Today is a snowy day, the blizzard hasn't over yet and it has been 5 days since the first storm start. The hallway was quiet, only the sound of the snowstorm rumble outside of the has gathered at the Central Command Room currently.

However, there is a girl sitting next to one of the window, she has pale-purple hair and her hair covered her right eyes. Her iris also has lilac color as well. The girl wore a common gray and white jacket with a hood. Beneath her unzipped jacket is a black dress with a white neck collar and a red tie decorated 2 conjoined diamond. At the bottom, she wore black tight pants and brown shoes and on her face is a pair of glasses. She is in deep thought until the sound an animal brought her out of her world.

"Fou! fou, fou, fou! "

The owner of the sound reveal to be a strange white creature. Is a long ears, little, fluffy white creature that somehow resemble a dog in a way. On ,it neck was sported a blue ribbon. The creature deep blue eyes look at the purple hair girl for a few seconds before turn around and ran away.

Seeing so, the girl put down her ipad and chase after the creature. The girl keep running along the quiet hall until she heard something: music. The girl wonder why there is a sound of music around here, and the melody brought her a feeling of peace and safe for some reason. Unknow to herself, she was attracted by the sound of music. She forget her pursued and just follow the sound until she spot someone sitting on a nearby bench, next to a vending machine.

The man look pretty young, he has messy black hair, he wore a white long sleeve t-shirt that contains 2 belts, 1 connects across his chest while other under his hip. At the bottom, he wore black pants with black shoes. On his belt hang 2 strange device, The device on his left side is a strange device with a holder at the bottom and a big blue ring at the top. There are 2 small wings at the opposite sides of the ring. The equipment on his right side is a silver card container with the blue ring at the center. On his right hand is an ocarina.

The white shirt man open his blue iris eyes and turn to his left, saw the girl. Both look at each other in silent for a few seconds before the man open his mouth

"Hello there …. Who are you? "

The girl close her eyes while put her hands under her chin

"That's a hard question to answer. Maybe I'm not important for you to know my name."

The girl open her eyes, and the man can see deep under those eyes is sadness.

"No, I do have a name. I have a proper name."

The girl turn around to look at the man again "But I never have a chance to use it … I'm afraid I don't leave a very good impression."

"Hmph … is okay, it doesn't matter if no one remember you. What matter is show them who you are."The man smile at the girl. For some reason, the purple-hair look a little away, blush by what the man said for some reason. Unknown to the girl, her heart beat faster by the man words.

The girl then turn to the man with a determined look "Ahem. Anyway, can I ask you a question, Senpai?"

The man nodded his head "Go ahead."

"What is that instrument? I don't have any data about the object so I don't know the function." the girl point to the ocarina while take a sit next to the man.

"This is an ocarina. I always play it when I have free time." the man answer but the girl notice there are some … nostalgia in his voice.

Suddenly, the strange white creature came out of nowhere and jump on the girl head. This surprised the man "What kind of dog is that?"

"Fou! Kyuuu! Kyoa!"

The white creature slowly move to the girl left shoulder and stare are the man with curious. "I've never seen an animal like that before." the man said as he look at the creature.

"This squirrel-like creature is Fou. He has a special right to roam freely around Chaldea." the girl answer while petting the creature with her finger.

"Fou!"

The creature jump on the man head then bounce back to the ground before ran into the unseen corner of the hallway. The man stand up, place his ocarina into his pocket "Such an interesting creature."

"Fou rarely approach anyone except me but it seems he's has take a liking to you, Senpai. Congratulation, now you shall be second caretaker of Fou in Chaldea." the girl stood up as well.

"Haha, that doesn't sound too bad." the man strange replied again baffle the girl.

"You hasn't tell me you name yet." the man turn to the girl, surprised her.

After saw some hesitation in the girl eyes, the man decide to take the initiate "Allow me to introduce myself first, my name is Gai K-!" the man suddenly put his hands over his mouth, before let out a nervous laugh, confuse the girl.

"My bad, let me do that again, my name is Ritsuka Fujimaru" the man show his right hand.

"You said you have "a proper name but it not important for anyone to know". That fine in my book, everyone has a name and it doesn't matter if it important or not." the man words once again make the girl blush for some reason.

Slowly reach her hand out, the grab the man hand, complete the hand shake. She could feel the warm light from his hand. She cannot tell what this feeling is but she could describe as a warming light that bring security and comfortable. She narrowed her eyes at hand, she want to understand this experience. Until Ritsuka voice awake her "So, what is your name?"
"My name is -"

"Mash! Mash Kyrielite!" an older male voice suddenly appear out of nowhere.

The man turn around to see another person approach them, the person is a 5 feet 9 man at mids-30. Green is all he wore with a top hat, a coat that lined with black fur. Under that coat, the man wore a dark green suit with white shirt and a purple tie that decorate with small spikes. The long coat almost hide the man brown pants and his high boots that almost reach his knees. He also has long hair that past his shoulder. His face seem approachable but it also hidden something wrong.

"So this is where you are." Fujimaru could taste the darkness that somehow leaked from the green coat man, but decide to let it pass anyway.

"Everyone is at the control room, come quickly." the man walk to the duo, until he notice Ritsuka existence.

"Oh, who are you?"

"Hello, sir. My name is Ritsuka."

The man pressed his strange bracelet, reveal a page of information about Ritsuka in hologram form "Ah, you are the 48th candidate. One of the common recruits."

Fujimaru let out a fake laugh to hide his pain when heard that word. He already knew that he just an average citizen that got invited to fill the number. But unknown to anyone, he is still waiting for the light to return.

"Please don't be disappointed. All of you are necessary for this mission." the top hat man making some strange gestures while speaking.

The man put his hand on his chest "I'm Leff Lynor, one of the engineers here."

"Why are you here? All candidates must presence at the Central Command Room for the orientation from the director." the man know as Leff ask.

"The director is not the type to easy forgive, you will be glare for the entire year if you show up late." Leff cross his arm with an amused smile.

"Ah yes, about that." Ritsuka scratch his head with a awkwardly smile "I don't know where is the Central Command Room."

"Senpai, follow me." the girl know as Mash grab Fujimaru hand, pull him and in a matter of the second, both of them, with Leff ran behind quickly reach the elevator.

Antarctica- Chaldea- the Elevator

While in the elevator, Leff could not hide his curiosity anymore and decide to ask Mash "It's unusual for you to involve with someone, Mash."

"What did you find so appealing about him, Mash?" Leff questioned Mash with hands behind his back.

The girl gazed at Ritsuka for a few seconds before replied "Because he seems … human"

This answer confuse Ritsuka and Leff but Mash quickly realize that and said again "Let me revise what I said. Senpai is the most human around here."

The girl turn to Leff "Everyone in Chaldea I feel … different for some reason."

Leff has an amused smile as he put his hand under his chin "Interesting".

As the lift coming lower, Fujimaru could see a massive room that act like a basement. Multiple black strange pillars-like structures could be see with the biggest stay in the center of the room. Ritsuka has saw many strange worlds and amazing technologies but this still impress him whatsoever.

Antarctica- Chaldea- the Central Command Room

Olga Marie Animusphere, the daughter of Marisbury Animusphere, who is the Lord of the Astronomy Faculty. She is a member of the prestigious Animusphere family of magi and one of the top ten families in the Clock Tower. This woman has a strange hairstyle. Her over shoulder long hair is pure white with a braids on her right side and her bang drop on the left side of her face and between her eyes. Her golden iris eyes go well with the color of her jacket. Behind the jacket is a white business shirt that connect with her white skirt and beneath is a tight pants with pale red wine color and black high heels. There is also a red cloth pinned on her shirt collar by a beautiful orange gem.

Currently, angry at someone is an understatement for Marie. She could feel her blood boil and her blood vessels explode at any moments. The Director could not believe that on her great speech for the candidate's magus, candidate # 48 has fallen asleep. His sleeping face just makes her eyes twitch in furious. The women have check Ritsuka profile through her bracelet, she should not expect any from this man.

"Another from the commoner's block." Marie scowling.

Without any seconds of hesitation or mercy, poor Fujimaru has been kicked out of the room. The man still pisses at the Director for disrupted his good dream, is been a long time for him to has a good dream. The man clicks his tongue in annoying. Ritsuka turn around to see the Control Room close and Mash walk to him.

"Senpai, you have been excluded from the first mission."

"Yeah, I knew that, Mash. You don't have to tell me." Fujimaru sighed.

"Very well, I'll take you to your room." the girl said.

Antarctica- Chaldea- the Hallway

The storm is still there and the dark cloud has blocked the sky for days, all could be heard is the screech of the blizzard through the windows. On the silent and cold hallway, the sound of steps is the only thing exist. Mash and Ritsuka walk in silence until the pale-purple hair girl decides to question the man.

"Senpai, are you gonna leave?"

The man didn't respond for a couple of seconds there.

"I haven't think about that yet."

"Oh, I see." the girl said softly.

With good perceptions, Fujimaru sees that the girl still has a question to ask him but it seem she's too shy to open her mouth.

"Mash, it seems you have another question for me, right?" the man question once again surprised the girl.

Mash stare at the floor for a short moments before face at Ritsuka with a determined look

"Yes, if you don't mind my question, Senpai"

"Go ahead." Ritsuka waved his hand dismissively.

"What are those devices on your belts, Senpai? I never see them before." the girl question make Ritsuka flinch for a second there. He never thought someone would notice his Ring. "This girl has good eyes."

The man has a sad smile while look at the ceiling "They are something that reminds me who I'm. They are the reason for me to remember my purpose and not forget my true self."

The man answers somewhat puzzled Mash but the girl could sense sorrow and pain in that voice. The girl looks at the man in sympathy. "These must be something personal to him."

After a few more minutes of walking, both have reached in front of the room. The purple hair girl point to this door "Here is your room, Senpai."

"Thank you, Mash"

"I have to go now. Take care, Senpai." the girl bow before hasty turn away.

"Good luck, Mash." the man wave his hand to the purple hair girl.

Antarctica- Chaldea- the Hallway-Ritsuka room

Ritsuka opens his slide door, and he did not expect someone already in his room. On his bed is a man. This man seems in early-30s and he wore a white coat that has an aquamarine stripe at the middle along with white pants and white shoes. Even his gloves are white. This man has pink long hair that tied up into a ponytail. Hang on his neck is his ID card.

He is currently sitting on Fujimaru bed and on his hands is a plate of strawberry cheesecake with a laptop on his thigh. Both men look at each other for a few seconds.

"Hello there" Ritsuka said awkwardly

"Yes, come in - Whaaaaat?! Who are you?!" the man exclaim

"This is an empty room, and my "hooky hang out"! Who gave you permission to come in here?!" the man point his fork at Ritsuka.

Fujimaru sigh "Sorry to disappoint you, this is my room now." the man answer deadpanned

"Your room?" the pink haired man look at his fork before realizing something.

"I see… so the last kid finally show up" the man put his hand on his face, let out a sigh.

"So ... who are you?" Ritsuka ask

"Oh, I'm Romani Archaman, head of the medical division. Everyone just call me Dr Roman. " the man answer with a smile while point to himself.

"Well, nice to meet you, Dr Roman." Ritsuka said with a bow.

"So, why are you here? I heard all staffs were involved with the Rayshift." the man ask curiously.

"Yes, about that ..." Ritsuka scratch his head with a nervous smile while walk to a nearby chair.

After 10 minutes of telling the story

"So in other words, you have been cut from the first mission." the man now know as Roman give Ritsuka a cup of coffee.

"Yes" Ritsuka answer before look at his hand "That dream, no doubt about it, the time has come."

"Then we're two of a kind." Roman smile before taking a sip of coffee

"The director chase me out, saying "every time Roman is here, the mood soften up"." the man look at Ritsuka sympathy.

"Oh really?" Fujimaru also takes a sip of coffee.

"But now since neither of us has anything to do. We should deepen our friendship." the man put his hand on his hip

"Sure ..." Ritsuka answer with a sweatdrop before both of them clink cups together.

After 1 hour of explanation

"... so that's the structure of Chaldea. An underground workshop built on a snowy mountain 6,000 meters above sea level." Roman finished his "details description" about Chaldea.

"Oh, I see ..." Ritsuka has a thinking look, almost 80% of his mind is somewhere else. His heart beat faster for any minutes, his fist clench tight. The man can feel something wrong happen, he has an uneasy feeling inside his gut. For almost 25 years of his life, he could feel the light slowly return to him.

Suddenly, Romani bracelet flash for a few times. The doctor press his devices as a hologram that show Leff voice put not his face.

"Romani here." the pink haired man answered his call as Leff voice could be heard from the other side "Romani, Rayshift will begin shortly. Could you come here, just in case?"

"Huh? What happened?" Roman ask

"Team A is ready but Team B are having small issues with some people who aren't used to this." Leff explained

"Then I'll anathesize them." the doctor suggested

"Yeah, hurry. You're in medical office right?" the green coat man questioned

"Yes" Roman replied nonchalant.

"You should be able to get here in two minutes." Leff urges before the screen shut off.

"But this is not the medical office." Ritsuka spoke

"W-Well, I won't get in trouble for being a little late." the pink haired man words make Fujimaru sweatdrop.

"Ah, the man I just spoke with is-"

"Professor Leff, right? I meet him earlier" Ritsuka said cause Romani to surprise

"He said he was an engineer here." Fujimaru explained

The pink hair man chuckled, confused Ritsuka "An Engineer? That was incredible humble from him " The doctor points his finger up while clarifying Leff job "He's the Mage who created the telescope to observe Chaldeas, the Near-Future Observation Lens, Shiva."

Ritsuka was surprised to hear this new "Shiva? Human technology never ceases to amaze me." the man has put his hand under his chin with a small smile.

"And, the former director is the one who constructed Rayshift summoning system." the man continue to illustrate Chaldea function.

"And Atlas Academy provided the Spiritron Calculation Engine to actualize the theory." Fujimaru quickly remembers what is Spiritron from one of the old books he has read a couple months ago.

There were a few seconds of silence between two of them as Ritsuka look at the floor at that moment "Human may not the perfect species but their intellect always the one that impresses me."

"So many talented people have come together to make it all possible." Roman crossed his arms as he gazed at the ceiling for a few minutes.

"Well, thanks for chatting with me, Ritsuka!" the doctor stands up as he walks to the door but looks back at Fujimaru with a smile "Next time, I'll treat you some yummy cakes if you visit my office."

Ritsuka was about to wave goodbye but something unexpected happens. A sound could be heard through the wall along with the ground began to shake and the lights instant turn off for some reason.

"BBBOOOOOOMMMMMM!"

"What happened ?" Romani ask with some concern in his voice.

"Maybe the power is out." Fujimaru replied while looking around the room but from the sound, he knew something bad just occur "This is the sound of an explosion."

"Impossible, Chaldea never suffer power outages before!" Romani said as he walks out of the room.

The lights on the hallway is flicker at a rapid rate while an alarm went off and announcement voice boom through the hallway "Emergency. Emergency. A fire has broken out in Central Power Station and the Central Power Room. Central Area's containment wall will activate in 90 seconds. All staff must evacuate from Gate 2 at once."

Romani quickly press his bracelet again, showing the direct camera view of the Central Control Room, and what he sees is only debris and flames.

"What the … ?" was the only words the man could form as he notices something through the screen "Only CHALDEAS is the only thing unharmed?"

"Mash! She still in there!" Ritsuka drops his coffee cup to the ground as he remembers his kouhai.

"Doctor! Can you lead me to the Central Control Room! I gotta save Mash!" Ritsuka exclaim as he looks straight into Romani eyes.

The man could see determination and conviction from Fujimaru eyes. The pink haired man nodded before both of them ran outta of the room with maximum speed.

5 minutes later

Antarctica- Chaldea- the Central Control Room

The door slides open as Romani and Ritsuka swiftly enter the room. However, the situation seems much worse than from the screen. Multiple blocks of stones fall from the ceiling, most of the staffs in the control have been killed by the explosion and all 47 candidates magus is stuck in a critical condition.

"It's possible this was an act of sabotage." Romani said grimly

"I agree." Ritsuka replied as he began to analyze the current situation "I wasn't wrong after all, that sound was a bomb."

Romani suddenly realize something as he turns to Fujimaru "I'll go to the Basement Power Plant" and without any seconds of hesitation, the man ran out of the room.

"Better look for Mash or any survivors" Ritsuka spoke to himself but a very familiar sound attract his attention.

"Ding, ding, ding, ding ..."

"That sound!" the man was surprised to hear the sound of notes right now, but then when he looked to his belt, his face turn from surprise to shock.

The Ring Device on his belt is flashing with blue and yellow lights, this can only mean one thing "The time has come, my light is returning!" the man grab the device from his belt.

Ritsuka looks at the Ring on his hand for a few seconds before putting it back onto his belt and ran to the center of the room.

Fujimaru approach the Coffin: Spiritron Chassis as he place his hand on the surface of the machine. The man face close his eyes as his fist clench tight and gritted his teeth for his failure "Their light - it fading away. Everyone is dead."

Abrupt from his thought, Ritsuka could sense a light, it was small and like other, it's slowly fading away from the existence. However, Ritsuka is not about to give up right now "There is still hope for this light."

The man swiftly climb through a block of stone to spot someone under a giant boulder. It was Mash, however, the girl half-bottom was stuck under the stone. And next to her is Fou.

"Oh no!" Fujimaru worst thought has come alive, the man quickly ran straight to the purple hair girl while shouting "Mash! Hang on! I'm coming to save you!"

"Senpai?" the girl weakly said as she looks to the source of the voice.

As Ritsuka approach, the man saw blood leak from the girl abdomen, his mind now filled with anxiety "This is worst than I thought, I need to act fast!"

Without any hesitation, Ritsuka tries to use his bare hands to lift the rock but the only thing he receives is burned hands.

The girl pleaded with the last of her strength "Please … you need to … run..."

"Save your breath, I'm gonna get you out of here!" Ritsuka exclaims with all his might as he tries again but fails. The man angrily look at his hands "Dammit! This body still needs time to be fit with my light!"

The man once again was brought of his thought when heard another announcement from CHALDEAS "Warning to observation staff"

"Another announcement?" Fujimaru look at the giant globe, the man knew that this announcement will not be like other, he could feel darkness is coming and it coming fast.

"Chaldeas' condition has changed" these words cause Mashu to look at CHALDEAS with fear and concern.

"Shiva's near-future observational data will be overwritten. The survival of humanity on Earth for the next 100 years cannot be future of humanity cannot be guaranteed." hearing this, Ritsuka now sure that his time has come, humanity is facing extinction and the only thing that can save them is his light.

Mash worst fear has become true when the bombing happens "Chaldeas is ..."

However, another unexpected announcement appears "Central bulkhead will now be seal." a giant steel gate quickly lock down as the announcement continue "Commencing interior cleansing in 90 seconds."

Ritsuka look at the door as his mind filled with more concerns "This is not good!" the man move his hand to the right side of his belt and pull the lever on his card holder clockwise, reveal multiple cards in the container.

Fujimaru glance at his kouhai and notice that her conditions getting worse by every second, the man couldn't tell what will happen next but he knows exactly what will happen to the girl. Ritsuka looks at his hand as it was shaking not from the stress but something he hasn't felt for a long time: fear and despair.

The man quickly pull out a card from his container and stare at it, the card has drawing of a strange silver being with the color of red and blue. Ritsuka clench his right fist tight as he closes his eyes while trying not to bite his tongue, he prayed "Tiga, now there is not enough courage, please grant me courage."

After a few seconds of silence, Fujimaru put the card back into the holder before pushed the level counterclockwise. The man stares at the ceiling before took a deep breath.

The girl looks at the man with a sad look "Senpai … I'm sorry … because of me ..."

Ritsuka was surprised by the girl words for a second there before replied with a reassured smile "Don't worry, Mash. We will find a way out of here."

The man slowly take a seat next to the girl while trying to remove fear from the girl "Are you okay there, Mash?" but his fist still clenches tight "poor girl, it should have been me, not her."

"Yes … thank you …" the girl said weakly

Another announcement comes up but Ritsuka has already ignored it. The man looks at the ceiling but turns his head to Mash when heard her voice again "Senpai … you can't see … the sky ...at all … from here."

The man eye with purple hair girl with sorrow but quickly switch to a wide smile "Don't worry, Mash, I will show you the sky with my light."

The girl's eyes were widened by these words, used the last of her strength, the girl raises her left arm "Senpai … I'm sorry… your hand."

The man, without any hesitation, grabs her hand with his left hand as his right-hand clenches tighter "This is the least I can do for her."

The ground began to shake fiercely and the fire quickly engulfs the room. Fujimaru closes his eyes "This is the end. If only the light returns to me sooner."

Singularity F

Fuyuki City

Time: A.D 2004

Ritsuka opens his eyes as he tries to stand up, the man looks around to locate Mash but found no sign of the purple hair girl.

"Where am I?" Fujimaru notice that he is not in the Central Control Room, or maybe even Chaldea, as from his eyes, the man only see destroyed buildings and he is standing on the middle of the street.

"A city?" Ritsuka quickly deduced.

Abrupt from his thinking, Ritsuka could hear the sound of arrows being shot from far away. The man doesn't know where is the source while trying to find a place to take cover. However, the moment Fujimaru gaze at the sky, he could see hundred of red arrows coming straight at him.

Ritsuka about to pull out his cards but something unexpected happens, Mash dashes out of nowhere and using her giant shield to block all of the attacks. The man was shocked by the girl strange attire.

"Mash?" was the only words he could form in his mouth.

"I'll explain later. But for now, please stay down." the girl replied seriously.

The moment the girl finish her sentence, another barrage of explosive red arrows appear, this attack decimated the ground around them.

Ritsuka close his eyes with a focused face "I need to locate the shooter!" in the next second, the man opens his eyes and exclaim "Found you!"

Ritsuka quickly pulls out one of his cards and aim it at the tower in front of him, this card has the image of a silver being with blue armor on his chest, forearm, and head. The card glows brightly with white-blue light as he activates its power.

"Ginga Fireballs!" Fujimaru yelled as he summons numerous magma like fireballs that appear around him simultaneously. The man uses his finger to direct the fireballs to hit the shooter, who on top of a tower that about 10 blocks from Mash position.

In a matter of seconds, the tallest tower in front of them was engulfed in a giant explosion, as the smoke died down, half of the tower was gone by the fireball attack. Unknown to them, another mysterious figure has watched the fight in one of the destroyed buildings.

The purple hair girl turn around and see that her Senpai is in a kneeling position while holding a strange card in his left hand "I never see that type of magecraft before."

"Mash, what with that outfit?" the man slowly stand up as he looks at the girl with a confused look.

The purple hair wore some kind of knight armor but too expose be knight armor. Her armor was painted with black and 2 purple horizontal stripes above her chest and 2 purple vertical stripes on her gloves and her long socks. Mash gloves reach over her elbow and her socks over her knees. The girl skirt is plain short and made of steel as well. The girl attire overall consists of a black skin suit protect by steel frame outside, except her stomach for some reason. Next to her is a giant shield that has the same height at her. The shield notable feature is 4 pieces of steel held out from the round frame, and the bottom piece is longer than other piece and the outside structure of the shield decorated with few pieces of jewelry.

The girl gazed at her armor as she tries to find words to explain "Um … this is ..." but got interrupted by a scream from the other side of the street.

Ritsuka face turn serious as he gazes at the location the sound came from "Mash, someone needs our help, get there first, I follow you."

"Hai !" the girl nodded before dash away with superhuman speed. After Mash disappeared from the man sight. Ritsuka sighs out of relieving that Mash still alive but confused about the girl newfound power.

"I figure about that later, now, I need to help Mash!" the man quickly dismiss those thoughts away to focus on the current issue. The man put swiftly switch to another card from his container.

This card contains the picture of a silver being with boxy eyes and solar panel cover his shoulder and chest. Fujimaru looks at the card in silence "Seven-san, please lend me your weapon."

"Fou!" the sound of Fou brought Ritsuka out of his thoughts as the man glance at the creature with a smirk. Fujimaru raise the card up as he shouts "Eye Slugger!", in a matter of seconds, the card instant reform into a strange crest-boomerang weapon.

The man turned to the white creature with a wide smile "Let's go, Fou!"

"Fou! " the squirrel-like creature immediately jump on Ritsuka shoulder.

In the next second, Ritsuka and Fou run to the source of the scream with maximum speed.

Meanwhile, with Mash

Director Olga Marie Animusphere was chased by a bunch of skeletons and running for her life. The young women have enough with these undeads so she decides to give them some of her Gandr shots but the sheer amount quickly overwhelm her. Fortunately, Mash Kyrielite come to the rescue with her shield. Even though the purple hair girl doesn't have any skills yet but her physical power was enough for these undead creatures.

However, before Marie grasp the situation happen before her, a strange boomerang came out of nowhere, hit a few skeletons skulls before return to Ritsuka. The director turns around to see candidate 48 holding the strange weapon with Fou on his shoulder.

"Director?" the man seemed surprised to see her.

"You?" the women exclaim

Mash quickly use the bottom of shield to cut the skeleton into 2 before smash her shield onto the ground, create a powerful shockwave that destroys the remaining skeletons. After that, the girl quickly ran to Marie "Director? Are you hurt?"

"What is going on?" the women ask fearfully

"This is Singularity F, Fuyuki, 2004." the purple hair girl replied

"Also, I think that-"

"You become Demi-Servant, right? I could tell just by looking at you. " the white hair women cut off the girl words.

While Mash and Director discuss her sudden transformation to Servant. Ritsuka looks at his Ring device after putting the card back into his container. Once again, the Ring was flashed with yellow and blue light for a few seconds there, Fujimaru face now has a smirk "Just a little longer."

"...commoner has become your Master." but Marie's voice snapped Ritsuka out of his thoughts

"Master?" Ritsuka looks at his hand, he sees strange runes on the back of his hand. The man was surprised and amazed for a few seconds there but quickly regain his composer "it seems these are … Command Seals if I remember correctly."

Abrupt from his thoughts again, Fujimaru bracelet begins to beep, the man presses the device as a hologram screen appears from the ground next to Ritsuka. The person on the screen reveals to be Romani.

"I finally got through? Hello, can you hear me?" the man voice was coming from the screen.

"Dr Roman!" Ritsuka exclaim

"Ritsuka, Mash! So you did get caught up in that Rayshift. Without the coffin-" Roman quickly got cut up by Marie.

"Why have you taken control, Romani?" the woman asks angrily.

"Director? You're alive?!" the doctor shouts in shocked

"What're you talking about? And why is the head of the medical section in that chair?" the white hair women crossed her arms.

"Where's Leff?" Marie could feel her patience run thin.

"Professor Leff was right in the middle of the explosion. I can't see any hope of his survival" Roman words immediately impact Marie to her core.

"No" the Director low her head.

While Roman begins to explain the current situation, the survival of the candidates and the future plan for Chaldeas, Ritsuka begin to see flashback. The light has returned to him, this means his identity and power has come back as well. Fujimaru decides to close his eyes and open it again, the man was shocked that Mash is not next to him and the environment is not Fuyuki but only a color of white.

Somewhere in Ritsuka mind

"This place, no doubt about it." Ritsuka turn around to see a man with a brown leather jacket and blue shirt standing behind him. Both men stare at each other for a few seconds before the fedora hat man said: "Ritsuka Fujimaru, do you still remember who you are?"

Ritsuka nodded "Yes, I'm you."

"Do you still remember your name?" the man aks

"Yes, our name is Gai Kurenai."

"Do you know who we are?" the brown leather jacket man snapped finger as multiple giants appear out of nowhere begin to surround both of them

"We are the giant of lights." Fujimaru replied as he glances at his hand

"We are the Sunset Wanderer."

The brown leather jacket man smile at Ritsuka before slowly disappear into the light "Welcome back, Ultraman Orb."

Back to reality

"Senpai?" Mash voice immediately brought Fujimaru into reality again.

"Sorry about that, Mash. What did I miss?" Ritsuka scratches the back of his head with a smile.

"The director said we will investigate Singularity F." the girl reported.

"Very well." Fujimaru nodded but his face turns grim suddenly "Darkness! I can sense it and this darkness is coming close!"

" Director, I detect movement are approaching us!" Ritsuka exclaim

"What, where?" Marie quickly stuck in panic mode again while Mash was confused about Ritsuka ability. However, for the next second, the girl glance at the nearby building, her face instant turn serious.

"I detecting enemy Servant!" Mash swiftly enter her battle stance.

"We need to get out of here!" Marie said as other two nodded in agreement.

Somewhere in Fuyuki- near Fuyuki Bridge

The trio has run for the last minutes. Director Marie still has a hard time to catch up other two. While Mash superhuman stamina keeps her on track, Fujimaru body has already changed, followed by the will of his light. The white hair women realize that they need to stay close to the river rather run through these streets.

"What the heck? What's a Servant doing here?" Marie frown

"It's a Holy Grail War." Mash replied while remaining her stoic face

"Holy Grail War?" Ritsuka surprised by the term "Holy Grail War", the man has heard and seen the Holy Grail before but that was a long time ago. However, this "Holy Grail War" is completely new, even for an ancient being like him.

Fujimaru look at his hand once again "The light will give me answer." the man closes his eyes for a few seconds before opening it again. He has found his answer.

"A powerful weapon for a human standard. But powerful nonetheless! This Ultras may has tried to corrupt this Grail!" Ritsuka was deep in his thoughts again without realizing the darkness is really close to him and other two.

"Senpai? Are you alright?" Mash voice once again brings the man out of his thoughts.

"Huh? Ah yes, never feel better!" the man scratch the back of his head while letting out a nervous laugh, trying to hide his concerns.

Out of nowhere, Ritsuka instinct kicks in as the man immediately turn to the left and saw a flash from one of the buildings on the window.

"Mash to the left!" the man exclaim as multiple chains shot out from the window.

Follow her Senpai words, the girl quickly dashes to the left side of Director Marie and raise her shield up, blocking the attack. The force behind the attack push Mash back a few feets.

"Ah! Fresh prey has come." Ritsuka could hear a voice echo through the air. The man sensed a great danger is upon him and his kouhai.

Suddenly,a strange women materialize in front of the trio, she looks at Mash and Fujimaru with great interest "An unknown Servant and unknown Master."

The women wore a black attire consist of a hood and slit dress. She has dark pink hair with rectangular shape pupils in her eyes. Her legs also have strange drawing pattern with the color of red. On her hand is a scythe with a spearhead at the end of the other side and a hunger smile. One of her special features is her impressive … asset, with similar size with Mash.

"How young and fresh" Lancer lick her lips.

Mash quickly ran in front of Lancer and prepare her shield "A Servant! But I don't see her Master ..."

"She doesn't need one, the darkness inside her was strong enough to hold her body in the physical realm." Ritsuka narrows his eyes at the enemy while activating his Card Holder.

"Darkness?" Mash was surprised to hear those words, the girl has a large amount of knowledge about the Holy Grail War but this "darkness" is new to her.

The situation getting tenser every with minutes pass by. Mash ready her shield while Director Marie equips herself with magic. Fujimaru has already held a card in his hand but then a voice whisper into his ear, the man could hear a dark and gravy voice along with the cold wind breeze into him."Your light shall be mine, Ultraman." the man eyes widened as he tries to look around to locate the voice but no avail, there is only silence.

"Fujimaru!" Marie's voice shout out immediately snapped the man out of his thoughts, "Are you try to get killed?! Focus!" the Director yelled with all her fury while Ritsuka put his hand up "My apology, Director. It won't happen again."

The sound of steel crash into each disrupt the duo conversation. Both of them turn to left side and saw that Lancer try to break Mash defense with her pokes attack but the purple hair quickly counterattack with a shield bash, which sends the pink hair Servant a few feets back.

Mash glance around her and instant spotted that Lancer has formed a square ring with chains around the trio with her chains. The girl speaks to her Master without turn her back to Lancer.

"I'm no match for her. Please run, Senpai." the girl knew how powerful is Lancer compare to her.

"Don't worry, Mash. We will get through this together." Ritsuka slowly reaches his Ring Device on his belt until another man voice chimed in out of nowhere.

"You've got guts." everyone, including Lancer begin to look around to locate the voice but found no result.

"A little girl is still a little girl, but you seem pretty strong. That's why I can't leave you like this." the voice continues, this cause Lancer to gritted her teeth in frustration.

"Show yourself!" the busty pink hair women yelled.

"If you said so ..." the voice replied before a small blue light shine on one of the destroyed windows of the buildings "... old friend."

It's revealed to be an adult male wore a blue robe that covers his bottom with a light-blue cloak over his shoulder. On his head is a fur hood and underneath the bare-cover cloak is see-through black clothes that show his muscle. He also wore a white segmented belt. Another feature is his lack of shoes and a strange wooden staff that had a club at the top decorate by charms. The man slowly pulls down his hood, reveal his long tied down blue hair that reaches his waist.

Lancer widened her eyes in surprise when she sees the blue hair man "Caster?!" the pink hair Servant points her finger at the trio while said angrily. "Why do you side with these wanderers?"

Caster give Lancer annoying looks before letting out a smirk "Because it's better being on your side, of course!"

Without any hesitation, the dark-red eyes man swipe his hands in a wide, horizontal arc, create multiple strange drawings. In the next second, the written runes were shot out like a canon at Lancer. This cause the pink hair Servant to disable her chains and jump up to dodge the attack.

While Mash and Marie still looked with awe, Ritsuka let out a small smile "Those runes! There is no mistake, he may look different in this world but the runes are the same."

Caster swiftly jumps next to Mash before walk closer, only a few feet, to Lancer who just land on a nearby lamppost.

The man points his staff at the pink hair women with a smirk.

"I'm a Caster Servant. For certain reason, I consider her an enemy. The enemy of my enemy is not necessarily my allies, but for now, you can trust me." the blue hair Servant spins his staff before switch into a battle stance while speaking to Mash without looking back "Get in position, young lady. Skill aside, your courage is second to none."

"Right " the girl quickly readies her shield.

Caster glance to his left as he spots Ritsuka "Hey buddy! Are you the Master?" the question caught Fujimaru off guard and the man only respond is a nod.

The blue hair Servant continues to speak "I don't know what are you but I'll leave it to you for the commands, for now."

"What? What does he mean by that?" Marie did not miss what Caster said, the white hair women glance at Ritsuka with a confused look.

"That's fine with me. It means I can kill you earlier than planned. I'll take you while you still fresh and blood." the pink hair Servant glare at the quarter with intense bloodlust before shot out multiple chains.

The blue hair Servant jumps up to dodge but detect more chains, with bigger size by twisting together, coming straight at him, force the man to move in body in mid-air to avoid the attacks. The moment Caster land on the ground, Lancer dash at the blue hair Servant with mad speed.

The pink hair Servant delivers series of slashes but Caster superior speed help him avoid all of the attacks. However, Fujimaru sees that Lancer is pushing Caster back with every strike. Frustrating, Lancer delivers a powerful swipe with her scythe, which causes Caster to do a backflip.

The pink hair Servant realizes that Caster could not dodge any longer, without any hesitation, the woman shot out a bunch of chains at the blue-hair Servant. Fortunately, Mash quickly dashes in front of Caster and shield him from the attack.

Lancer click her tongue as she jumps a few feets back. Without any warning, Caster swipes his hand again, release another barrage of fire runes. However, the pink-hair Servant has prepared this time and swiftly use her chains to as a barricade to protect her from the attack. A large explosion occurs from the runes which send both Ritsuka and Marie a few feets back, as the smoke died down, Lancer reveals to be fine thanks to her chains.

"Damn, look like she got a new trick." Caster clicks his tongue with an annoying look at his opponent.

Let out an evil smirk while spinning her weapon, the busty pink hair Servant spoke "This is what you get for open your big mouth. Now die!"

The moment Lancer prepares to strike again, a voice was shout out, cause everyone to turn their head to the source of the voice, reveal to be Ritsuka, with a smirk while holding a card with the picture of another silver being. This being has a diamond shape blue gem on his chest and red lines ran to the abdomen which forms a V shape on his body.

"Not on my watch! Mebium Burst!" the man raise his card over his head as a giant large ball of fire is form. Everyone was taken aback from the manpower, especially Marie "what is that magecraft?"

Lancer immediately jumps up to dodge but was sent back to the ground, after a few meters height, by a barrier. The pink-hair Servant turns her head up, only to see a strange blue magical circle above her head. Lancer turns her head to the blue hair Servant while look at him with fury.

"Don't think you're the only one with new trick." the blue haired man said with a smirk.

Before Lancer could do anything else, the fireball has already hit her, resulting in a giant explosion that almost destroys half the street and almost everything around with the radius of 8 meters.

As the smoke died down again, Lancer was gone, her entire body has been obliterated by the giant fireball. Marie opens her eyes again, reveal Mash has protected her while Caster uses his runes to shield himself. Meanwhile, Ritsuka was fine, which shocked both Mash and Marie, again.

"Senpai, are you alright?" the purple hair girl slowly approach the man.

"Don't worry, Mash, I'm -"

But Fujimaru words quickly got cut up by Caster with a serious expression "Alright, I got a question for you."

Ritsuka was flinched and surprised by the blue hair Servant sudden mood change as the Director angrily chimed in "Back off, Caster! I have a question for him too!"

"What do you want to know, Caster?" the man said with sweats drop from his face.

"What are you?" the blue-haired man question Fujimaru.

Ritsuka glance at a confused Mash and a furious Marie before look at Caster again "Guess I can't keep this a secret anymore."

The man let out a sigh before open his mouth "Very well, first, my real name is-"

Suddenly, the ground began to tremble for some reason while everyone tries not to lose their balance. everyone, especially Caster, looks around and then to each other.

The blue hair Servant presses his staff onto the ground and forms a giant magical circle under everyone, the rune instant negate the earthquake. After that, Caster begins to look at the damaged buildings and everything else that damaged by the short earthquake. The blue hair man narrows his eyes at a nearby building and quickly spot that the structure was shaking very intensely "What the hell?"

Before everyone could grasp the situation, a large monster emerges from the building that Caster is looking at. Mash immediately pull up her shield, Caster prepare his staff and Marie was trembling with fear by the sight of the giant creature.

The 203 feet tall creature is bipedal. The creature skin was cover in a thick organic rock-like layer. The beast has a large tail and his shoulder was buff, along with his arm in a natural way. Another feature is red veins could be seen on his chest that spread around his body and also strange red gems on his large legs. But the strangest part of his body is his head, the creature neck has the shape of a pyramid that protects his face with forehead held out.

"What the hell is that?!" Marie shriek out while her body begins to shake.

"And I thought Berserker is a monster." Caster gritting his teeth.

"Senpai! Director! Please stay back!" Mash rapidly ran in front of Marie and Ritsuka.

Fujimaru widened his eyes with his jaws almost drop down "Golza! How a kaiju is here?! " the man quickly grabs his Ring Device on his belt.

The monster know now as Golza let out a large roar as purple energy could be seen running through the creature thick neck. It didn't take a genius to realize what the creature about to do, everyone quickly ran to nearby rubble on the pavement to take cover.

In the next seconds, a powerful beam was shot out, carving the street like a hot knife through butter. After a couple of seconds, Caster peeks his head out from the rubbles and saw the devastated street and buildings by the monster beam.

"Alright! You want a fight?! You'll get a fight, you bastard !" the blue hair Servant jumps out from his cover before release another flames runes attack at the monster face.

The giant beast roar from the attack before shot another purple beam, but weaker, at Caster but the man speed help him dodge the attack. "Caster!" Marine shouted out, and her voices gain Golza attentions.

The moment Golza fire another ray at the trio cover, Mash raise her shield instantly, blocking Golza beam. Fortunately for the purple hair girl, this is a weaker version of the previous ray the damage wasn't significant.

"Senpai! Director! Are you okay?" the girl asks without turn her head. While Marie nodded, Ritsuka begins to do something that everyone, except Caster, though is suicide.

Fujimaru just run straight at the monster as Marie yelled out "Fujimaru! What are you doing?!"

"Senpai!" the purple hair girl prepare to chase after her Master but Caster places his hand on her shoulder.

"Don't worry. He knows what he's doing." the blue hair Servant reassures the girl while staring at the beast.

Ritsuka raises his device up as a white light engulfed him.

Before the giant monster could deliver his attack again, the light from the Ring Device stun him and force everyone to cover their eyes.
