Chapter V: Evil Awakens I

Zero used his Aegis Armor for the second time to transport the two of them back to Earth after Father of Ultra and Ultra Seven allowed them to leave. Mirai flew behind her brother in silence, trying to wrap her head around the other Ultras she had just met back on M78. She wasn't going to admit it, but seeing Daichi again made her happier than she had been in the past few days.

"Are you thinking of someone?" Zero asked from beside his sibling.

"Maybe," Mirai said in response.

"It's Daichi isn't it?" her brother teased.

"H-How did you know?"

"I can see it all over your face little sister. You like him don't you?"

"I just think X has a unique appearance compared to the rest of us!" she tried to defend, finding herself blushing and was furiously glad her Ultrawoman appearance couldn't give it away.

The older Ultra could hear the embarrassment in his sister's voice and refrained from teasing her further. In retrospect, Zero was glad his sister was finally opening up and accepting her heritage as an Ultra. Though the protective side of him wanted to hide her from the other newer Ultras, but seeing how she was starting to warm up to Daichi, maybe it would be best if she got to know the latter better.

"If you like him, you should tell him."

"Aniki!"

Mirai covered her mouth with her hands and hid her face when she realized what she just said unconsciously.

"Did you just call me aniki?" Zero asked, crossing his arms and smirking.

"S-Shut up!" Mirai muttered.

"I'm happy you called me that Mirai. It means you're starting to accept me as your brother."

"Don't expect to hear it too often idiot."

Zero chuckled to himself and the duo continued on their journey.

Ultraman Hikari joined the rest of the entourage halfway towards the Monster Graveyard.

"Hikari, how is Mebius doing?" Gai inquired from the front.

"Mother of Ultra managed to stabilize him. He's resting for now, but if he pushes his limits he'll be on bed rest for at least a month."

"I see. Then I hope we find the source of this darkness before any more harm can come to the other Ultras."

"This evil is cunning, it hides itself and attacks when we are not aware. When we arrive at the Monster Graveyard, we are to be vigilant."

The others nodded in agreement.

"Up ahead," Ginga said as they came upon the Monster Graveyard.

The group landed at their destination and slowly began making their way around the perimeter.

"There's a very strong presence of Minus Energy here," Hikari noted as the air grew thicker around the group.

"I can hardly breathe in here," X commented.

Katsumi and Isami were in the rear of the group as they trailed behind their seniors, the siblings having never been in a place such as the graveyard. Even Riku was somewhat frightened of the place.

Something suddenly struck Isami across the chest, causing Ultraman Blu to grunt in pain and look down to see where he had been attacked.

"Isami!"

The others heard the commotion and rushed over to the siblings.

"What happened?" Victory asked of the siblings.

"I don't know. S-Something attacked me," Blu replied as Katsumi helped his brother stand.

Without warning, Geed clutched his head and stumbled backwards from the group as a black cloud swarmed over his body.

"Geed!"

"Something...something is trying to take control of me!" Geed yelled, his head threatening to burst with the intense pain he was feeling.

"We need to purify the darkness from Geed before it consumes him!" Hikari said.

Ginga, X, and Victory stepped forward with Victory assuming his Knight form.

"Ginga Comfort!"

"Purify Wave!"

Victory joined in by playing a melody on his Knight Timbre and the others watched anxiously, hoping the light would be able to disperse the evil that was looming towards Geed. The melodies surrounded the black cloud but Riku cried out in pain as the darkness constricted his body. A shockwave emitted outwards from Geed's body, destroying the light energy and knocking the other Ultras onto their backs.

Orb was the first back on his feet and immediately he realized something was wrong with Geed.

"Riku! Are you alright?"

Geed's normally blue eyes had turned a dark red, reminiscent of his possession by Belial.

"Riku!"

Hikari grabbed Orb's arm as the latter tried to move towards his friend.

"Stop. He's been possessed by the Minus Energy," the older Ultra warned.

"We can't just leave him like this!" Orb argued.

An ominous voice echoed around the Ultra warriors at that point and the group was on high alert.

"This body is mine at last! Belial's blood served its purpose at last," the voice came from Geed.

"Who are you? What have you done with Geed?" Hikari demanded, instantly taking an offensive position while the others did the same.

The mysterious figure controlling Geed turned to look at the group of warriors, and in the blink of an eye, attacked them before they could even have a chance to react. That one attack alone was enough to turn their blinkers red, and left them struggling to get up from the ground.

"Not bad. I like this body," the imposter said.

"Release Geed this instant!" Hikari tried to stand but fell on one knee.

"You call yourselves Ultra warriors? Don't make me laugh. One attack and you're all blinking red, I thought the new generation of warriors would be stronger than this. Seems I underestimated you all," Geed scoffed.

"Riku! I know you can hear me!" Gai grunted, pushing himself to stand.

"Riku? So that's this boy's name eh? Shame. He can't hear you anymore. From now on, I'm in control of this body. You know me very well, Ultraman Hikari."

Hikari lifted his head in confusion at that point.

"That voice...it can't be..."

Geed cackled maliciously and disappeared into a wormhole.

The members of GUARD were more than happy when they finally saw Mirai arriving back on Earth alongside her brother. A Mecha Gomora seemingly appeared from nowhere and wreaked havoc upon the city. None of their missiles or blasters were any good against the giant robot, and the group were forced to switch to hit and run tactics to buy time until Mirai returned from wherever she was.

"Mirai!" Sakura shouted, breathing a sigh of relief as her friend flew past already transformed.

"What is that thing?" Mirai dodged out of the way as a missile came flying towards her.

"Mecha Gomora, I fought one once back when I met an Earthling named Rei."

"Tell me later," Mirai landed on her feet and lifted her hands, standing alongside her brother as the siblings faced off against the robot.

-M78-

Father and Mother of Ultra were alarmed when they saw the badly injured group returning from their scouting mission to the Monster Graveyard.

"Hikari! Everyone! What in the world happened?" Father of Ultra rushed over to support the warriors.

"We were ambushed...by something...and Geed was taken," Orb said.

"Taken? What do you mean taken?" Mother of Ultra held her hands against her chest in worry.

The Plasma Spark slowly began restoring their energy and the color timers on their chest gradually stopped blinking. The warriors were able to stand up and allowed the Silver Cross members to inspect them for further signs of damage.

"Empera Seijin," Hikari said, looking at Father and Mother.

"Empera Seijin was destroyed by Mebius. Why are you saying his name all of a sudden?" Father of Ultra questioned.

"Empera Seijin is the one who possessed Geed," Hikari finished.

Everyone turned to look at Hikari at that moment.

"Nii-san...did you say Empera Seijin?"

Mebius slowly made his way towards Hikari and the others, a hand clutching his lower left waist in pain, every movement causing agony to his already injured body.

"Mebius! You shouldn't be moving in your condition," Mother of Ultra hurried over and tried to heal the young Ultra but Mebius shook his head.

"Is it true?" Mebius asked, eyes locking with Hikari.

"Yes."

Mirai grunted as she was thrown backwards into a building after Mecha Gomora shrugged her off its back. Zero changed into his Luna Miracle form and took over for his sister, giving her a chance to recuperate. Forcing herself to stand after being thrown, the Ultra studied the robot carefully, looking for signs of weakness or an opening to strike. It seemed Zero had everything under control since he was more than a match for the robot.

She was about to join back in the fray when a stranger landed in front of her.

"Zero-chan, duck!" the figure shouted.

Her brother seemed to recognize the voice and rolled over out of the way as a fireball hurtled towards the robot.

"Watch where you throw that Glen!" her brother scolded.

"Uh..." Mirai stood there awkwardly.

"Who do we have here?" the stranger turned and leaned in to study her intensely.

"Idiot! Stop flirting with my sister," Zero growled, smacking Glen upside the head.

Mecha Gomora took this chance to launch an ambush attack on the trio but Mirai managed to see the robot charging up for an energy shot.

"Aniki!"

Jumping in front of her brother just as Mecha Gomora unleashed a energy ray towards them, Mirai threw up a shield and tried to block the attack but the ray grew in intensity, eventually forcing her feet to inch backwards bit by bit.

"Mirai!"

"Kill it now!" she screamed, her timer blinking rapidly in red.

Her brother and his friend immediately leaped into action and unleashed their strongest attacks on the robot, succeeding in blowing it up. Mirai dispersed the shield and fell on her knees panting heavily.

"Mirai, are you alright?" Zero knelt beside her.

"I'm fine. Just tired," she replied wearily.

"Oi Zero-chan, since when did you have a sister?"

"Since oyaji told me about her. Now why the hell are you here? Where's Mirror Knight and the other two?"

"They went to visit the Princess. I stuck around for a bit but got bored and left to find you. Now are you going to introduce me to your sister or what?" Glenfire asked, lightly smacking his friend on the shoulder.

"Ugh. You give me a headache," Zero rested his forehead on his hand briefly.

"Mirai, meet Glenfire. Glenfire, meet Mirai, my younger sister who is also Ultrawoman Corona."

"Ultrawoman Corona eh? I guess she took the name from your Strong Corona form?" Glen asked, swiping a hand over his head and causing fire to erupt briefly.

"Oyaji was the one who named her. Has nothing to do with my Corona form."

The Garuda Strike Team flew overhead at that moment, interrupting the conversation as Mirai waved to them.

A shadowy figure observed silently from afar, having witnessed the battle between the two Ultras and the Mecha Gamora they had sent.

"Ultrawoman Corona..."

The figure hadn't counted on a new Ultra appearing to defend Earth. The last Ultra to do so had been Mebius, and he had already departed after defeating Empera Seijin. Ten years had gone by without a trace of a new Giant of Light to protect this planet, but it seems they were wrong.

Zero showing up only served to complicate matters even further.

"I must get rid of you two...to revive my beloved Zera. No one will stand in my way," the figure swore.

A gust of wind blew through at that moment, lowering the hood to reveal a young man in his mid-twenties with an angry-looking scar going down the left side of his face from his forehead down towards his eye. Both his pupils glowed bright red the longer he continued staring at the Ultras.

"Soon Zera...soon we'll be together again," he murmured, cradling a pendant in his hand.

The pendant glowed softly for a brief moment before going dormant.

To be continued...
