Y/N POV

I wake head with my head feeling dizzy. My vision is blurry and my muscles are sore. I try to move but for some reason I can't. I look down to see my hands and feet are chained to a chair. I take note of my surrounding and notice that I'm in a dark room with a single light shining over me. I start tugging on the chains to try to brake them but I notice they're made of quinque steel. I try to activate one of my kagunes but cant. Memories start to come flooding back to me.

Y/N(thought): Where the hell am I? Why did Jason bring me hurry? Who the hell had him bring me here?

These questions go through my mind until I hear someone talk.

???: There's no use in try to get out, this area is heavily secured.

The voice is feminine but also a bit static, probably using a device to disguise her real voice. Then from the shadows emerges a girl wearing a purple cloak and has her entire body covered in bandages.

Y/N: Who are you, I'm guessing you're with Aogiri Tree?

She nods in response

???: You're smarter than you look for someone who spent their entire lives in the street.

Y/N: So why am I here exactly?

???: Let's start off simple, my name is Eto and for why I brought you here will be revealed future.

Y/N: Really, you're gonna that kind of person,

Eto: I will tell you this one thing. You and I are more alike than you realize.

Y/N: What's that suppose to mean?

Eto: You'll see, but for now let me ask you this? Haven't you wondered how a ghoul can be half human and have three different kagunes, both of which are extremely rare.

Y/N: You're guess is as good as mine.

Eto: Perhaps if you were to know who your parents were.

Y/N: You know who by birth parents are?

Eto nods in response

Y/N: THEN WHO ARE THEY!

Eto: Sorry but that must remain a secret for now.

Y/N: GOD DAMMIT!

I start to tug on the chains more aggressively. A man wearing a cloak and mask entered the room and whispered something to Eto. Eto then approached me.

Eto: Sorry Y/N, but out time together must be cut short.

In an instance she karate chopped my neck knocking me out.

I wake up again, still in the chair. I can hear gun shots and explosions in the distance, most likely from the CCG. I try to break out but no luck. I try to activate my kagune but no luck. However I feel my rinkaku start to emerge. I use most of my energy to get a single tendril to emerge. I maneuver it so it can pick the lock on the handcuffs. It works as I move the ones on my ankles. As I get up from the chair I smash down the door and run through the base.

Y/N(thought): I have to find Kaneki. Who knows what psychotic things Yamori is doing to him.

I run through the base checking room after room for Kaneki. As I open the door to one room I end up in a giant dome. I look around and see a chair next to a table in the middle of the room. As I approach the chair I see all of the dried blood on the floor.

Y/N(thought): Please be alive Kaneki!

???: Isn't this quite unfortunate, I was hoping to play with Kaneki one more time. But unfortunately he's broken out. However you'll do.

I turn around and see Yamori standing there.

Y/N: Where is Kaneki Yamori!

Yamori: I wish I knew, I was having such fun with him.

I slowly become pissed off

Y/N: What..did..you..do?

Yamori: Oh you know the usual. A classic beat down and slicing along with finger removal and a nice centipede in the head.

Y/N; YOU BASTARD!!

I got to leave but Yamori kicks me back.

Yamori: Sorry but you're not leaving that easily.

He activates his rinkaku and tries to slam me. I jump into the air and use my bikaku to cut his cheek which quickly regenerates.

Yamori: Is that really the best you got, a single cut

I then activate my rinkaku. Me and Yamori charge at each other. I go in for strikes but he blocks my attacks. I manage to slice him a few times with my rinkaku. I leap into the air to avoid a sweep from his rinkaku. But the other tendril comes around and smacks me into the ground. Yamori leaps into the air and lands on me. He then proceeds to pick me up by the neck and choke me.

Yamori: I got to say, I'm rather disappointed. I thought you would put up a fight.

I become light headed. Luckily my ukaku comes to life as it fires shards at Jason. He drops me as I take this opportunity to attack. Using all of my kagunes I slice, shred, and cut him. He tries to dodge but with my ukaku I'm faster. I go for the finish by hitting him with all of my kagunes. He goes flying into a wall.

Y/N: Did I win?

I was interrupted by a weird sound coming from where Yamori landed. As the dust clears I see Yamori being wrapped in tendrils. I realize it's a kakuja.

Yamori: You think you could beat me that easily! Oh no, no, no, no! I'm gonna devour you! I'm gonna eat your flesh! You hear ME! YOU'RE DINNER!

Yamori roars as he charges at me. He is much faster now. I do my best to dodge but he is quicker. I try to block but his muscles overpower by kagunes. I get thrown around as he repeatedly punches and kicks me back and forth. Each time I spit out a little blood. He hits me hard in the gut as a go straight up. Yamori leaps into the air and smacks me into the ground in a crater. Yamori lands next me as he steps on my back breaking it. I scream out in pain

Yamori: What's a thousand minus seven

He proceeds to break my legs

Y/N: 993...986...979...972...965

I hear Yamori laugh at my pain

Yamori: Hard to believe you're an SS rated ghoul.

He continues to shatter my body. He then picks me up by my hair.

Yamori: I heard that Anteiku is here with everyone in it, even that little girl you're so fond of. Would be a shame if she were die, slowly and painfully.

Yamori grins and laughs as he sees my eyes widen. He chucks me into a wall.

Y/N(thought): No, not Hinami. I can't lose her. She's I got left along with rest of Anteiku. I can't lose this feeling in me. You hear me! Į wøñt FÄÏŁ!!!

I feel a strange feeling surging throughout body.

No POV

Y/N's body starts to cover in scale like material. From his head sprout two horns. A mask covers half of his face. A light emits from his shoulder blades as two tendrils pop out of his back. The tendrils are covered in spikes and at the end resembles a dragon dead.

Y/N(distorted)

Yamori charged at Y/N ready to punch him, but in a blur Y/N used his new kagune to slice Yamori across the gut. Y/N laughed psychotically as he and Yamori charged at each other. It was a blur, kakuja against kakuja, murder against demon, sparks from the clashing were flying everywhere. Yamori grabs Y/N but Y/N whips the tendrils around and lodges them it Yamori's shoulder. Y/N kicks back so the tendrils shred Yamori's shoulder. Yamori stumbles back as Y/N uses the tendrils to launch him forward and lands a powerful kick in Yamori's stomach sending him flying back. Y/N rushes but Yamori regains his ground and smacks Y/N away. Yamori leaps into the air only for the end of Y/N's tendrils to open up revealing two mouths full of fangs. The heads grab Yamori and throw him away, ripping off a part of his kakuja in the process. Yamori regains his ground and throws a series of punches at Y/N. Y/N manages to block all of the attacks while cutting Yamori in the process thus ripping more of his kakuja off. Yamori manages to uppercut Y/N high into the air as he to leaps upwards. However Y/N's tendrils fire multiple shards at Yamori that impale him. The tendrils grab Yamori's legs and throw him into the ground leaving a crater. Yamori attempts to get up but Y/N's tendrils start to glow as a bright beam fires from the two dragons heads right at Yamori. This attack creates an explosion. Y/N lands on the ground. As the dust clears it reveals Yamori down with his kakuja destroyed. Y/N jumps onto Yamori's back as one of the dragon heads bites into his back. Yamori cries out in pain.

Y/N:

The other tendril starts to bite Yamori.

Yamori: 993...986...979...972

The dragon heads continue to rip apart Yamori.

Y/N:

Y/N starts to dig into Yamori.

Timeskip

Aogiri Tree ghouls were charging at CCG officers as they fired their guns. All of a sudden Y/N crashes through the floor still in his kakuja form.

CCG: What the hell is that?

Ghoul: Is he on our side?

Y/N laughs as he whips the tendrils around shooting everyone around him, thus killing them. Outside the Marude was watching in horror at the scene that just happened.

Marude(thought): What the hell is that? It's killing both humans and ghouls.

Y/N continues to laugh, all of a sudden the grounds starts to shake. The building begins collapse. Y/N tries to destroy the falling debris but is overwhelmed as he gets crushed.

Y/N POV

I wake up with my head hurting and muscles sore. I don't remember what just happened. I try to move but couldn't.

Y/N(thought): Man am I back in that chair?

However I soon realize that I'm covered I rubble. I do my best to move. The rubble starts to move as I start to see sunlight. I crawl my way to the top, once there I burst out from under gasping for air. I look down to see I'm shirtless and my pants are now shorts. I look around me and though the dust I catch a glimpse of Eto. I walk around to find my out of here. I walk away from the destruction. In the distance I see someone familiar, it was Touka. I rush over to her.

Y/N: Touka are you ok?

Touka: Y/N you made it out!

Y/N: Answer my question.

Touka: It's Kaneki, he said he's joining Aogiri Tree.

Y/N: WHAT, why is he doing that?

Touka: I don't know.

Y/N: Where are the others?

Touka got up and lead me towards everyone else. Hinami looks up and runs toward me pulling me into a hug.

Hinami: Y/N you're ok! I thought I would lose you to.

Y/N: Don't worry, I'm not giving up my life just yet.

Koma: Good to see that you're still kicking.

Nishiki: Hey where's Kaneki?

Y/N: I feel like should explain that back at the shop.

NO POV

As the sun starts to rise, it reveals the wreckage of the battle that just happened. The CCG was searching the rubble for any survivors while helping those who are injured. Any reaming members of Aogiri Tree run in the opposite direction. Elsewhere we see a group of ghouls filled with glad and worried looks walk back the place they call home.
