NO POV

Kishou Arima was walking through the empty halls of the large building. He stopped for a few seconds and started to head towards the door.

Guy(comms): Sir where are you heading?

Arima responded to the man.

Arima: Dont worry about it, continue with the operation.

Arima walked out the doors and entered the forest behind the building. He walked deeper into the forest and stopped in a large opening.

Arima: Good to see you again Y/N.

Y/N leaped down from the trees and removed his mask, revealing his left kakugan.

Y/N: Hey Arima...been awhile.

Arima: Two years, I've hoped that in that time you've become stronger.

Arima then brought out Narukami(that's the one that shoots out lightning) and placed it next to him.

Y/N: Yes, I have spent my time getting stronger. I may not be as strong as I am in my kakuja form, but here I have complete control over myself.

Y/N dashed at Arima and started throwing various punches and kicks. Each attack Arima effortlessly blocked with a single hand. Arima elbowed Y/N in the gut and then kicked him in the head. Y/N got back up once again and continued with the same attack. Arima blocked each strike again. He then punched Y/N threw times in the chest, uppercutted him, and finally punched him hard enough that he fell to the ground.

Still Y/N got up and charged at Arima. When Y/N got close Arima stepped to the side, getting out of Y/N's way. Arima picked up Narukami and slashed Y/n across his chest. Y/N stumbled back and Arima fired a ball of lightning which hit Y/N square in the chest, making Y/N fall on one knee.

Arima: If you wish to fight me, you better use everything you got. Otherwise I might not let you live.

Y/N wiped the blood off his lip.

Y/N: You got it.

All three of Y/N's kagunes emerged. Arima fired more lightning and Y/N blocked with his ukaku, which then fired shards. Arima used his blade to block the attack, and then the two charged at each other. Y/N used quick attacks with his rinkaku and bikaku, which Arima blocked. At the same time Y/N used his ukaku to block the lightning from Narukami. The two met in a standoff as they were pushing against each other. They both jumped away from one another.

Arima: Well done, you can now use all three of your kagune with ease.

Y/N: That's not the only thing I learned.

Faster than the eye could see, Y/N charged so fast that I even caught Arima off guard. Arima just barely managed to dodge the attack. Y/N reappeared behind Arima. A cut formed on Arima's cheek as blood started to dribble down.

Arima: This has been one of the few times a ghoul has managed to land I hit on me, let alone blood.

Y/N: Now will you start fighting seriously?

Arima: Very well.

Arima shot lightning at Y/N who jumped into a tree to avoid. The two became blurs, it appeared as if they were vanishing and reappearing. Arima continued to fire lightning at Y/N. Y/N in return leapt from tree to tree and fired his shards. The speed of these two was incredible. The area around them started to break from their battle.

Y/N jumped down from the trees and landed back on the ground. He and Arima charged at each other, suddenly vanishing and reappearing behind each other. The ground beneath them broke from the force of their power. The two just stood there, suddenly blood shot out of Y/N's upper back.

Y/N fell to one knee as he put a hand over his wound. It was revealed that Arima had managed to cut Y/N's ukaku kagune, thus destroying it. His ukaku then shriveled up. The two turned around and started their battle up once again.

Y/N continued fighting with his rinkaku and bikaku. Arima still used Narukami to fight. Y/N tried to stab Arima with his kagune while Arima decided to go on the defense. They moved to fast you could barely even see them. Arima jumped back and shot a ball of lightning and Y/N used his rinkaku to block. The force of the attack sent Y/N back. From the smoke Arima emerged and slashed Y/N across the chest. Arima then quickly started cutting up Y/N some more, also sliced apart his rinkaku and bikaku.

Y/N fell to one knee as he tried to catch his breath and heal his wounds. His body was covered in cuts and blood was leaking from all of his wounds. Arima started to approach him.

Arima: You were very impressive, deserving of a SSS rating. However, I must do my job.

Y/N got up and ran at Arima, lazily threw punches at him. Arima kneed Y/N in the gut, making him cough up blood. The force of the attack lifted Y/N in the air. Arima got ready to finish this but felt a sharp pain in his shoulder. He looked over and saw a large blade going through his shoulder. He looked up and saw that this blade was attached to Y/N.

Y/N spun around and kicked Arima square in the back, knocking him away.

Arima: When did you get a koukaku?

Y/N: Last year, developed it through cannibalism.

Arima: It's a shame I didn't bring IXA, would've loved to fight you with it. Were both busy men that have a mission to complete so why dont we wrap this up.

Y/N grinned.

Y/N: I couldn't agree any more, and I know just what to do to finish this.

A red light started to emit from Y/N as the wind started to pick up. When the light vanished Y/N was in his first kakuja form.

Y/N: Let's do this!

Y/N started to rapidly fire RC blast, causing huge explosions. Arima dodged each one and fired balls of lighting. Explosions were happening all around the forest. Finally Y/N charged up a large ball of concentrated RC cells and launch it while Arima fired a large ball of lightning. The force of this attack created an even larger explosion.

Arima emerged from the forest, his coat was covered in dirt and the area were he was stabbed was stained with blood. When the other doves saw this their eyes went wide. They all went over to him.

Dove: Sir what happened?

Arima: I had a run in with the Demon, he managed to get away.

The doves were speechless. The great Kishou Arima was injured in battle. He even had a hole in his shoulder.

Dove: Should we go after the Demon sir?

Arima: No need, he's already gone.

Y/N POV

I tried to run but my leg was limp so I had to walk. By now the whole battle was over, and the humans mainly won. They rescued the humans and killed most of the ghouls. However thanks to me some of the higher ranked ghouls and Big Madam managed to escape. I finally got back to the where Aogiri agreed to met up. When I arrived the other ghouls ran over to me and help me walked. I sat down on a log and was approached by Nagi and Ayato.

Nagi: Damn what happened to you?

Me: I had a run in with Arima.

Their eyes widened.

Nagi: You fought Arima!

Me: Not only that, I made him bleed.

The other ghouls started to talk about what I said. I looked around and couldn't see Hinami.

Me: Hey where's Hinami?

Ayato looked down and grunted in anger.

Ayato: She's been captured by the doves.

Me: Wait what?
