Thoughts

-Madara-
-Ainz Ooal Gown's Conference Room-

Madara Uchiha was currently not a happy camper. His mood was fueled by the certain events that took place in this miserable world. First, that Uzumaki brat had the audacity to send him to another dimension. Second, this new world was just as dangerous, even more so, than the Shinobi World and this time he couldn't do anything about it.

This world, this terrible miserable world, was called Earth and it's brown sky and hazardous air made him cough violently. But he had to survive, he had to adapt, that was a shinobi must do when faced with an unorthodox situation.

That was 13 years ago. Now he stood at the top, a CEO of a large company, his past troubles were non-existent. His company held 100 businesses around the world.

It was also 13 years since he first logged into the VRMMORPG, YGGDRASIL. VRMMORPGs was a new hobby of his that he found enjoyable when he was off. His love of battle and warfare were set free in YGGDRASIL, his battle skills and reflexes were maintained, and the numerous ways a person could control their environment gave him numerous choices in his battle environment.

The NPCs and other players gave him the adrenaline of a fight. Combine that with the fact that the players were practical on par with him, made for tactics that he would not have thought of in the Shinobi World.

His scythe - the only weapon that he felt comfortable besides the katana and the gunbai - slew hundreds of players and thousands of bosses just for the sake of satisfying his lust for battle; earning him the rather lame nickname "the Battle Reaper."

His reputation increases, even more, when he was accepted into the guild, Ainz Ooal Gown, the once most powerful guild. He joined when it was in its prime, the time when it had 41 members. Now, it is rated the 4th strongest guild due to the lack of members logging on.

Madara and the guild master, Momonga, were the only ones who stayed after the decline of Ainz Ooal Gown.

Currently, Madara's avatar was seated down in a comfortable chair on a long elaborate table. He and Momonga made small talk as they sat in a comfortable silence.

The time was 11:23, twenty-seven minutes before the end of YGGDRASIL. "Say, Madara-san. Why do you play this game?" Momonga asked his bony jaw not matching his words.

Madara Uchiha shrugged at the question, "mainly for entertainment but I guess it was partly to satisfy my thirst for a good fight."

"Why waste your time and money on a virtual game? I mean you are the CEO of one the biggest companies in Tokyo. I'm, on the other hand, just a regular salesman," the skeletal master asked.

"Why do you waste your time and money on this game?" Madara replied with a glare. When no reply came the Uchiha admitted, "I find the real world dull and boring."

Momonga's avatar's jaw opened, but no reply came out.

"I'm gonna blow the rest of my money on decorations," Madara declared as he sat up and walked out. His fellow guild member sat silently before long HeroHero logged on.

-Madara's Quarters-

The lone Uchiha opened the grand doors of his quarters. His personal butlers and maids bowing at his presence. "Follow," he ordered, which they obeyed.

The walls of his entrance was that of concrete and wood, giving that mix of European and Japanese look. The floor was carpeted marble and the lavish furniture gave it a majestic aura fit only for a king.

Soon, he passed by his personal soldiers, the Black Soldiers corps. The Black Soldiers were separated into three groups, the infantry, the archers, and the mages with the infantry being the biggest.

The infantry wore full plated enchanted armor with all the same enchantments of enhanced strength, durability, and HP, they wielded long swords and rectangular shields. The archers wore light but durable gear and wielded a black bow that could one shot a level 20 player and when the need arises, a set of blades. They were created with less strength and durability than the infantry but they had higher agility and perception. The mages were divided into two groups and were the smallest group; the healers just healed and wore armor that increased the power of healing spells while the battle mages used powerful spells from a little bit shorter distance than the archers to attack the enemy, they wore armor that enhanced their mana and efficiency of spells.

He off-handily ordered them to follow him as well.

He stood in front of a huge door that led to his throne room and his study. It was 11:53, not much time left.

The grand doors automatically opened for the Uchiha as part of the game's easy mechanics. "Black Soldiers, guard the door," he commanded which the soldiers followed without question.

The throne room wasn't very grand compared to the guild's throne room but it still was elegant in its own right. The room was made out of a mixture of polished stone and wood. The floor was made of blackened marble. The throne was made out of black wood which was purchased by the gold that he got from selling his enemies' dropped gear. Two holes filled with lava let loose to a stream of lava which passed through a cash-shop teleporter that went to the lava pit in the room behind him that fed back to the holes.

Madara smirked silently as he sat down on his throne, his guards not moving a muscle as they processed that their master was on the throne. His guards, called the Grey Guard, was comprised of angels and demons that fell - like any other NPC that he made - under his automatic jurisdiction. They were separated by an invisible line that segregated them from each other. The angels on his right and the demons on his left.

11:59:45 P.M

"Well it has been fun playing this virtual world," Madara stated out loud which resulted in an echo. He could hear the distant cracks of fireworks going off outside of the tomb, undoubtedly they were the result of the developers celebrating the end of the game.

11:59:57 P.M

Madara closed his eyes, fully intending the force log out to log him out.

12:00. 12:01. 12:02. Wait.

"Hm?" Madara blinked open his eyes as he took a look at his surroundings, fully expecting to see his dark game room. Instead, he found himself still in his throne room in YGGDRASIL.

"So the developers pushed the time back," he mused out loud. "Naruto-" Yes that blonde haired Uzumaki "-fetch me General Izuna and Hashirama," the Uchiha commanded.

"It will be done! Believe it!" his whiskered blonde butler bowed in respect before hurrying to do at some he was told. Honestly, that voice is v-

Madara blinked. "He spoke?"

"Something wrong my lord?" A voice asked from the right. The Uchiha's glance bored into the helm of the angel who spoke, his face turning in confusion.

Quickly putting his hand out to access the menu, nothing happened. No menu.

What is this...Madara did not continue his thoughts as the two people he requested entered the throne room.

"Yes my lord?" Izuna and Hashirama asked as they kneeled before him.

Shit... Madara cursed silently. "I need you, Hashirama, to get an attachment of Black Soldiers and secure the area of the tomb, I feel something is amiss," he commanded coolly, his face now neutral. Hashirama ran to do as he was told.

I need to test something. Madara thought silently. "Izuna."

"Yes my lord."

"You are my brother, when we are in private, call me your brother or what not," Madara ordered as he watched Izuna shift uncomfortably.

"My lord, what about the Gre-" Madara cut off Izuna with a glare.

"They are an extension of my will, thus they are my sons, your nephews," Madara retorted. "The Black Soldiers and Hashirama are just people under my command that I have created. Granted that makes them my sons, that includes you, but let's forget all of that nonsense and you call me brother."

"Yes, brother," Izuna breathed out with great reluctance.

"Now that's out of the way, may you accompany me?" Madara asked as he got up and walked over to the opened doors. "I have to talk to Momonga-san about something."

"It will be an honor, my lord."

-Ainz Ooal Gown's Throne Room-

When Madara arrived at the throne room, no one was there. Not a single soul was in the throne room if that wasn't a scrutinizing enough, based on the little maids and soldiers, Momonga headed to his quarters.

"{Message} Hashirama: are the troops posted?" Madara asked.

"{Yes my lord, the Black Soldiers have secured the perimeter. However, we have a problem.}"

As I thought, spells work by focusing "mana" and calling out the name. "Oh?"

"{We are surrounded by grasslands, Lord Momonga was already notified by Sebas-san.}"

Madara's eyes widened a fraction at the revelation. The Great Tomb of Nazarick was surrounded by a swamp, not by green grasslands!

"Very well, keep me posted every hour," Madara said coolly. He then dispelled the {Message}. "Izuna, secure the floors with the reserves.

"Yes my lord." Izuna then took to the quarters.

"{Message} Momonga: Momonga-san, have you been notified of our current situation?" Madara asked over the {Message} spell.

"{Madara-san! I'm glad you're here! Did you post your personal troops outside?}" Momonga asked, however, his voice was darker than what you would think would be from a young adult male. Now thinking about voices, he sounded younger than what he would usually sound like.

"Yes, my troops will secure the tomb from invasion for the time being. My reserves are moving in to reinforce my men that are already there. I will personally oversee them," Madara declared.

"{That's good. I did not think that the {Message} spell works! How did you do spells?}"

"Distribute your mana to a certain point and release it in your image, though saying the spell name would help your concentration. For example, if you say {Fireball} it will do the spell," Madara stated as he cast the second level magic at the wall. The flames splashing and scorching the elaborate wall but the many spells of the Tomb started to repair the damage, albeit slowly. He felt a little part of him leave him but it quickly was diminished.

I wonder if I have chakra.

"{I have ordered all the floor guardians to assemble in the arena on floor 6}" Momonga revealed, "{I was going to ask you personally if you wanted to join me.}"

"An assembly of the floor guardians... are you going to address something to them?" Madara asked coolly.

"{Something like that.}"

-Momonga-
-Level 6's Arena-

"Albedo and the others are loyal to me like their original settings. Then, what about the other NPCs?" Momonga mused as he walked out of the dark corridor and into the Coliseum. "The two dark elves that Chagama-san should be the guardians here..."

"Hup!" A voice exclaimed from above. A figure jumped up and landed in a crouching position before him. "Victory!" The dust settled to reveal Aura, the female loli crossdressing dark elf. Aura then rushed over to him.

"Aura."

"Welcome, Lord Momonga!" Aura exclaimed as she gave a polite slight bow. "Welcome to the floor in which we guard!"

Momonga looked down at the small dark elf and apologized, "Sorry but I will intrude for a small while."

"What are you saying! You are the lord of the Great Tomb of Nazarick! It's absolute ruler! There is no one who would ever consider you intruding!" She exclaimed with a bright smile.

"By the way..." Momonga trailed off as he looked around for Aura's cute cross-dressing brother.

"Mare! You're being rude to Momonga-sama! Come over here!" Aura yelled with a fiery look in her eye.

"I can't sis..." A voice replied that would be almost inaudible to a normal human.

"Mare!"

"F-Fine!" Mare replied as he jumped down from where Aura jumped from.

The two of them are lively, I wish Chagama-san could see his characters. "Aura. Mare. Help me with some practice," Momonga stated.

"You'll be practicing Momonga-sama?" Aura asked.

"I'm testing this staff's power," Momonga replied simply. As he inspected his staff, the staff of Ainz Ooal Gown.

"T-That's... the staff of Ainz Ooal Gown!" Aura and Mare exclaimed in awe.

"Do you mind?" Momonga asked.

"Not at all!" Aura exclaimed in excitement. She put her fingers to her lips and whistled for the level's monsters. A pair of them appeared with straw dummies and they planted them down a few meters away.

Well rather than test the power of the staff. I'm testing my ability to use it. Momonga admitted to himself. He pointed his bony finger at one of the dummies and spoke, "{Fireball!}."

A large ball of fire appeared and fired off and hit the dummy. Madara was right. I can cast spells by calling out their name. "Perfect," he smirked inwardly.

"Lord Momonga, shall we bring more targets for you?" Aura asked from behind.

"No th-"

"Oh? Is something happening already?" Madara asked coolly from the entrance of the Coliseum, cutting off Momonga. Instead of wearing his iconic black robes and dark red armor, he now wore a simple black tight shirt and pants with red plates covering his shoulders, his waist and his legs (Madara's outfit from Naruto Shippuden before he got revived and absorbed the ten tails). His already shoulder-length hair seemed to increase in length rapidly.

"Lord Madara!/M-Madara-sama," Aura and Mare greeted.

"Ah the crossdressing elves made by Chagama-san, it seems that he liked his traps and reverse traps," the Uchiha mused as he made his way to them.

"Madara-san! You're just in time for the testing of the staff," Momonga stated with a look, his bony face and emotion trigger disabling him to show his emotions.

"The staff? So you're finally using it, that's a relief," Madara said with a scoff.

"Yes, this thing costs a fortune for the guild to make, that was before you came in with money blazing!" Momonga exclaimed but suddenly a bright green light surrounded him like a healing spell and his voice went back to a neutral tone. The light was ignored or was invisible to the two guardians of the floor.

Madara took in the sudden change of tone and light for later consideration. For now, he responded with a question, "so are you going to test it or not?"

"Hmph. Very well, {Summon! Primal Fire Elemental!}" Momonga called with a grand tone as he pointed his staff at one of the remaining dummies. A fire surrounded the dummy before it disappeared and a creature known as a {Primal Fire Elemental} appeared in its fiery form.

Madara scoffed at the heat. "May I?" He asked as he walked towards the elemental. The Uchiha didn't need confirmation as he created a single sign. I wonder... "Fire Style! Great fire annihilation technique!" He called as a large number of flames sprouted from his mouth, enveloping half of the Coliseum.

The elemental did not waver as it was immune to the heat of the flames, but that was a mere test. "Hn. Water Style! Water dragon technique!" He called as he flashed 3 signs, showing his less control over water than fire. Prior to intruding, Madara placed 30 water jugs by the entrance just for this test. A massive dragon made from the water from the jugs, roared as it charged at the elemental and ultimately destroying it as it crashed into it.

When he was done with his test he walked back to his guild leader. "I have never seen those spells before, never have I know that you were hiding high-level spells from me," Momonga accused.

"It was released on the last day of YGGDRASIL as a final screw you update. I was interested so I bought the spell tomes for all of them using all my leftover currency," Madara completely lied.

"Oh? Well, I was too busy looking at everything to check the update log," Momonga admitted. "Though it is weird that they would update this game on the final day."

Aura and Mare were understandably confused but did not comment on the strange phases of their 'Supreme Ones' exchanged with one each other.

"I know," Madara shrugged.

An ever-changing portal appeared suddenly. A figure stepped out of the portal. "My, am I the first?" The guardian of the 1st, 2nd, and 3rd floors, Shalltear Bloodfallen, asked a smirk plastered on her pale face.

The vampire walked diligently over to the group. As she got near them Aura muttered with a glare, "Fake boobs."

Shalltear spun around, while grabbing her chest, and shouted with a deep blush on her face, "H-How did you figure it out?!"

"Isn't it obvious with how full they are?"

That reminds me, Chagama-san and Peroroncino-san were siblings... Momonga deadpanned as the two went into a full-blown argument.

"Silence! You don't have any yourself!" Shalltear shouted with an embarrassed fury.

"They'll grow soon enough," Aura retorted.

"You are before milord, Madara-sama, and Momonga-sama!" A new voice bellowed with anger as he moved out of the shadows and walked to join the group. The voice belonged to Obito, the captain of the Red Guards, who's NPC race cost way over the average level 90 NPC kit.

Aura and Shalltear then realized where and whose presence they are in. "My deepest apologies!" They both shouted and at the same time.

"What is with all of the commotions?" A deep icy voice asked as a huge blue insect-like being approached. Cocytus, the guardian of the fifth fifth floor, released an icy breath.

"A little fight broke out between Shalltear and Aura," Obito replied with a little disdain in his voice.

"My apologies for the wait," the guardian of the 7th floor, Demiurge, said grin, Albedo a step in front.

"Looks like everyone is here," Albedo stated as she closed her eyes and shifted a small bow. "Now then. Everyone pledge our loyalty to our supreme leaders."

Shalltear took a step forward. "The guardian of the first, second, and third floor, Shalltear Bloodfallen. I bow before the supreme ones." She knelt on one knee.

Cocytus took a step forward. "The guardian of the fifth floor, Cocytus. I bow before the supreme ones." He too knelt on one knee and released a icy breath.

Aura took a step forward. "The guardian of the sixth floor, Aura Bella Fiora."

Mare took a step forward. "A-Also the guardian of the sixth floor, Mare Bello Fiore."

"We bow before the supreme ones," they said in unison as they knelt down with an arm crossing their hearts.

Demiurge straightened his posture. "The guardian of the seventh floor, Demiurge. I bow before the supreme ones." The demon knelt down and crossed his heart with his arm.

"The leader of the guardians, Albedo. I bow before the supreme one." She knelt down in a similar fashion as the rest.

"Leader of Madara-sama's Grey Guards, Obito Uchiha. I bow before my master and his accomplice." Obito then knelt on one knee a bit away from the rest.

Albedo stated her final piece, "Other than the guardian of the fourth floor, Gargantua, and the guardian of the eighth floor, Victim, all of the guardians and Obito-san have gathered before you. Please bestow orders upon use, Supreme Ones. We offer our complete loyalty to your majesties."

Both Madara's and Momonga's eyes shined red.

-Prologue End-

A new story. Prologues or the beginning of a story is always hard to write for me.

I'm not going to update UNSC GATE in a long time I just getting bored of it (as I get bored easily). There was another crossover of Overlord x Naruto but I decided against uploading it. I've been busy trying to come up with a good crossover with a good plot.

Also finished my wrestling session a few months back.
