OOO: Accel World: The Multi-King

A young man, who was about 15 years old, brown hair, and with clear features that he is half Japanese and half American. His name was Andrew Hino. He was wearing modern nomadic clothes and a strange device around his neck called a Neuro Linker. Right now he was following a guy around his age with dull blonde hair, with some of the bangs sticking out, and a red gauntlet that seemingly faded away in a red glow. His name was Ankh.

Originally Ankh was a Greeed, a creature created by desire, which woke up for the first time in 800 years. Unfortunately the only thing that regenerated was his arm so he had to find a host. Which he did but the down side…a part of his host is still active and can talk in him. However since Takumu was wounded he can't survive ten minutes without Ankh. Ankh met Andrew while a Yummy, a monster created by a Greeed, tried to kill them. In a last minute effort to save themselves, Ankh gives Andrew the power that hasn't been seen in 800 years: the power of Kamen Rider OOO.

The two were walking around until Ankh hears a noise from a device around his collar.

"It's probably my friends…I should teach you how to access-." Before Takumu could finish Ankh places his Greeed hand on his head. Ankh soon saw all of Takumu's memories especially how to handle technology. "W-What did you do?"

"I looked through your memories." He then looked at Andrew and a devilish smile grew on his face as he opened the interface and started going through the apps.

"Wait, what are you doing?" Takumu asked but Ankh ignored him.

"Andrew, how old are you?"

"Fifteen."

"How long have you had that device on your neck?"

"Since I was born. Funny story, my parents-."

"That's all I wanted to know." He soon got a cable out. "Connect your Neuro Linker with mine."

"It's mine and if you're doing what I think you're doing-."

"Shut it!" Ankh thought.

"Okay…" Andrew then connected it. Usually only couples do this but Andrew is well aware that no one is around to see them. Soon after a few seconds Ankh started looking through the apps until he found what he needed.

"Ankh, no!"

He then sent a copy to Andrew.

"What's this? Brain Burst?" Andrew wondered when he saw the icon and the prompt of whether he will install it or not.

"Just accept."

"Not until you tell me what this is." Andrew said.

"A game!"

"A game?"

"Yes, now just accept it. I gave you the means to save us earlier ago. At least humor me." Andrew found it odd that someone like Ankh would want him to play a game.

"But it's the student's…"

"It's just a copy don't worry besides I'm sure he can send another soon. What's the worst thing that can happen?"

"Should I name a few?" Andrew just looked at it before shrugging. While he doesn't completely trust Ankh it was weird for him to send a game over to him but he doesn't see any harm from it.

"Alright, Ankh, I'll play but know this; I'm not planning to be your tool." Ankh just stared at him. Andrew then clicked Accept before it seemingly exploded with the installation bar filling up quickly before it was done. It then said 'Welcome to the Accelerated World.' in front of him. Ankh soon disconnected the wire between them.

"Accelerated World? What is that?" Andrew asked before he felt a slight pain in the back of his neck and passing out.

Ankh just stared at the sleeping Andrew. While flicking his Greeed arm.

"Do you know what you just did!? And I could only do that once!"

"Yeah, I found a way to make him stronger. Besides technically you and I are different people. Most of your mind is mine so the application could read me as a different person." Ankh answered.

"Well, when you put it like that."

"Good, now I have to see how far humans have evolved in this era."

"Aren't you forgetting something?" Ankh looks down at Andrew's unconscious body. Ankh sighed before he started to drag it.

Andrew finds himself getting up from the ground. The place he is in was in ruin and hears the crying of children. His eyes widened as he recognized it.

"That voice!"

He soon started running for it. He sees faint images of what appears to be a little boy and girl. He reaches his hands out for them but soon several explosions occurred near them.

"No!"

Andrew soon sees the children gone. Andre got on his knees and started crying before screaming.

Andrew wakes up in cold sweat near a tree.

"About time you woke up." Andrew looks to see Ankh on the top of the tree. Despite Ankh looking like he's pressing the thin air. He's actually on the internet looking up what he can.

"What happened?"

"You passed out."

"No, I felt a pain in the back of my neck and then…" Andrew then looked at Ankh in realization. "You knocked me out!?"

"My bad." Ankh sarcastically said.

"Why did you do that!?"

"Because…I wanted to do that." Ankh answered.

"Really?"

Ankh got down from the tree.

"How long was I out?"

"An hour, while you were out I was mastering this." Ankh pointed at the Neuro Linker. "Apparently you humans have evolved so much. I managed to capture a whole bunch of information without even asking. Now…" Ankh looks at Andrew. "Are you connected to the Global Network?"

"Yeah."

"Good, then it shouldn't be long."

"I have a bad feeling like this."Taku said.

"Long for what?" Ankh looked at Andrew.

"You'll see." Just then everything went blue for Andrew and Ankh. The next second everything around them was being rebuilt and they all looked like ruins.

"What happened?" Andrew then looked at mirror near him which revealed him in armor.

The helmet was mainly black, save for the red faceplate which looked like a hawk with its wings spread out in flight. On his forehead and acting as the hawk's beak was a red crystal and his head had green lens eyepieces. Running from his chin and down his neck was a red line that was connected to the top portion of the image on his chest. The torso armor had rounded shoulders that had yellow lines on them. Yellow lines ran down his arms and into the yellow gauntlets decorated with what looked like folded claws on the forearm. Lastly the legs were minimally covered with segmented green armor not unlike that of a grasshopper's legs, connected by green lines to the lower section of the crest. Last was his belt that was rectangular and had three coin slots. In the slots were Taka Medal, Tora Medal, and Batta Medal. This was Kamen Rider OOO TaToBa form.

"I'm in my OOO Form!" OOO remarked.

"Interesting." OOO looked at Ankh. Ankh had his Greeed arm along with a body to match it. Ankh was examining himself. "It appears that I've managed to have a complete body here." Ankh observed as he was in his true Greeed form.

"Wait, is this the game you were referring to?" Ankh nodded.

"This is Brain Burst, what intrigues me is that humans created a world for violence to take place in."

"So you wanted me to play this so you could train me?"

"I need you in the best shape possible." Ankh said before a blazing message appeared in front of them.

"HERE COMES A CHALLENGER!"

"Wait I have to fight a player?" OOO asked before he noticed other players watching him. He then sees Ankh jumping onto the roofs of one of the buildings.

"You better win." Ankh said. OOO looks up to see what appears to be his health bar and his name, Kamen Rider OOO. Soon a countdown appeared counting down from 1800.

"Kamen Rider? I actually like it." OOO stated. In front of him was another player. He appeared to be a gray dullish robot with what appeared to be power armor. OOO looked at the name and apparently this character was named Gray Titan.

"You picked a bad day to come here, newbie." Titan said while getting his guns out. Soon a text appeared in front of them.

"FIGHT!"

Titan started by shooting at OOO. OOO was running as fast as he can while his legs started to glow green. OOO soon used the Batta Medal's power and jumped around at high places. Titan tried firing his missiles but kept missing.

"Stop moving around and fight."

"Okay." OOO soon jumped and performed a bicycle kick to him with the Medal's power. Titan crashed into a building before a good portion of his health went down. Titan soon thrust himself towards OOO with energy blade and tried to cut him.

OOO's Tora Claw gauntlets activated and OOO defended himself with his claws. OOO then kicked him before slashing at him. As his health was going down Titan quickly slashed at OOO. OOO flew and landed with some of his health gone. OOO also notices the Tora Medal blinking again.

"Ankh! I need the other medal!"

"Idiot! I don't have it here!" Ankh said. OOO then felt an aura coming from his Medal Holder on his left. He opened it and he sees a light green Core Medal with a grasshopper inscription on. OOO placed his Driver back in its original position for getting the Tora Medal out. This catches everyone's attention.

OOO placed the new Medal in, tilted the Driver, and scanned it with the O-Scanner. Huge holographic Medals appeared in front of him.

"TAKA!"

"KAMAKIRI!"

"BATTA!"

Three images of a hawk, mantis, and grasshopper appeared and formed into one symbol before going on OOO's chest. His head and legs remained the same but he now had a pair of mantis sword-like claws.

Titan and everyone else were surprised.

"Who is he!?"

"How is he able to do that!?"

"What kind of Armament is that?"

Ankh, however, remained watching in silence. Meanwhile an armored figure was watching as well. He had a black bodysuit, a blue shark–themed helmet, with a sea–blue whale themed shoulder design and has a few markings on his hands and a red wolf-fish boots that has spikes all over its boot. He also wields a harpoon known as Deepest Harpoon which it serves as his primary weapon. And on his waist was a belt that had three medals in the middle in a triangular position. This was Kamen Rider Poseidon.

OOO summoned his Mantis swords and quickly slashed against Titan. Soon about 75% of his health was gone. Titan soon went into the buildings. OOO looked around until the visor of his helmet glowed red. OOO started seeing through the buildings until he spotted his target.

"Going somewhere?" OOO then jumped into a window, grabbed Titan, and threw him out. OOO soon got the Tora Medal and switched again.

"TAKA!"

"TORA!"

"BATTA!"

"TATOBA! TA-TO-BA! TATOBA!"

Everyone became confused why there was a song but Poseidon and Ankh ignored it. OOO soon got his Scanner and scanned his Medals again.

"SCANNING CHARGE!"

A red, yellow, and green circle appeared in front of OOO in that order. They seemed to be going down and were directed at Titan. OOO jumped and after passing through the red ring he is surrounded in a red veil with wings, then the yellow ring which him gave an aura with claws, and finally the green ring which gave him an aura with legs. OOO aimed both of his legs as he charged.

"SEE-YAH!"

OOO collided with Titan causing a massive explosion. He emerged unharmed as Titan's health was completely gone. All that was left of Titan was a countdown for a respawn. Everyone was cheering while OOO bowed. Ankh just stared at him with a smiled while Poseidon left through a Gray Mirror.

Soon Andrew and Ankh found themselves back in the real world in the same exact position they were in at the exact same time they left.

"Ok, I'll admit that was little fun." Andrew said.

"And quite useful for training you." Ankh said before he left. "Surprised you haven't said anything." Ankh said. Andrew knows that he isn't referring to him but the student.

"How did it all come down to this?"Takumu replied.

(Elsewhere)

Poseidon exits the Gray Mirror and assumes his hooded human form. He was on top of a building and a blond teenage boy approached him.

"Yo." The boy greeted.

"Kazari, what are you doing here?"

"I got bored at the hideout, wanted to see how the last 800 years changed." Kazari explained. Kazari was the Feline Greeed and the most distrustful one.

"How did you know I would be?"

"Coincidence. So when are you going to get our Medals back? Along with revenge against Ankh?"

"In due time, for now, just follow my lead."

(Later)

Later in the day after defeating a Yummy, Andrew and Ankh continued walking.

"Hey where are we going?"

"To find shelter."

"I don't think my parents would be open to this."

"I could just use force." Ankh suggested. While Ankh and Taku were inwardly arguing Andrew just stared at them.

"Someday, I'll find a way to separate them."Andrew thought.

Soon the two ended up near a school and everyone was leaving. Andrew needed to seat down to think about how he's going to deal with this while Ankh was standing against the same wall but not too far with both arms behind his back until…

"Taku!"

Andrew soon sees a girl with brown hair, a short fat kid, and a girl with long black hair looking at Ankh.

"Taku, something is going on with Kuroyukihime. She's making a spectacle out of Haru here!"

Ankh just looked at them with a confused expression.

"Who are these humans?"

"Well that's Chiyu and Haru. And-."

Ankh soon changed his arm to its Greeed form. Andrew and Taku can see where this is going.

"Ankh, wait!"

Andrew became speechless until he saw Ankh's arm. He started running towards him.

"Ankh! Stop!"

AN: That's my OOO story. I hope you like it. Also I have decided on a pairing which is Fuuko. Also think of Andrew as an AR version of Eiji. The two have similar pasts and the same ideals. Anyways, just review or contact me and I'll get to you soon. Don't forget to view my other stories (Which I plan to update next). In case you're wondering, the final scene takes place at the end of Episode 2 of Accel World and that Andrew was able to use the other Medal so easily in Brain Burst is that each Medal is a part of OOO, once he uses it in the real world his mind is slightly adjusted so his Medal can be unlocked in the game. That's it, I'm done, goodnight.
