Akui, A being made out of Black and Dark Red flames and a part of Kaneki's soul thought he had destroyed all of his fellow fragments.
But as he destroyed their bodies, they turned into their truest forms before attacking him all at once and mixing together to become one.
And now...
Akui: KILL YOU! I'LL KILL YOU!
Kaneki: ...
The last Battle between Kaneki and Himself has begun.
Burst!
Akui: RAAAAAAAAAH!
Akui charged at the Kaneki in front of him with all his rage behind him.
Boom!
Shake~!
For each step he made inside of Ryueki's soul.
Everyone: WOOOOAAAAH!
Natsuki: What's going on?!
Ryueki: AAAAAAARGH!
Ryueki's thoughts*
(What is this feeling?! It hurts! It burns!)
His charged affected everything outside of Ryueki's soul causing the Stadium to shake a little, and caused immense pain for Ryueki.

Akui: RAAAAAAAAAH!
Slash!
Akui slashed his sword made out of his own flames at the Kaneki very violently.
Clang!
But it was immediately blocked.
Burst!
By Kaneki's own sword made out of its own flames.
Kaneki: .egnever deen t'nod uoY .hguone enod ev'uoy ,hguonE
Akui: Shut up! Shut up! Why won't you just die already?! Don't forget we're the reason why-
Kaneki: I am well aware of that, you don't need to keep repeating that excuse.
Akui: Shut up! Shut up!
Kaneki knew very well that Akui wasn't planning to listen.
Kaneki: i see, let's settle this now then. One last time.
Burst!
Punch!
Kaneki created it's own body and landed a powerful punch on Akui.
Crash!
Sending him crashing away.
Akui: AAAAAAAARGH!
Grip!
Dash!
As he was sent flying, Akui grabbed onto the ground and stopped himself before dashing back towards Kaneki.
Swoosh!
And Kaneki did the same, they both rushed towards each other very quickly.
Slash!
Clang!
Upon reaching each other, they began exchanging blows with their swords.
Akui: HAAAAAAAA!
Akui send out slash after slash, but.
Kaneki: ...
Clang!
Kaneki was able to counter them.
Punch!
Punch!
Boom!
When he tried resorting to hand to hand combat, Kaneki sent out his own punch and countering his.
Akui: GRRRRR!
After seeing his attacks not affect him one bit.
Boom!
Burst!
Akui's flames exploded and grew bigger.
Kaneki: Hmm~
Boom!
Burst!
And Kaneki did the same. As both of their flames grew, the shape of their flames changed.
Swoosh!
Akui: ROOOOOOOOOAAAAAAAAAAAAR!
Akui had turned into a a massive Dragon made out of his Black and Dark Red flames.
Kaneki: ROOOOOOOAAAAAAAAR!
And Kaneki did the same, he turned to a Dragon similar to size and type as Akui and made out of brighter colored flames.
And after the two transformed into Dragons.
Chomp!
Crash!
They immediately went back to fighting.
As they clashed, they destroyed everything on their way.
Ryueki City was being demolished by these two powerful beings.
Akui: DIE! DIE! DIE! DIE!
Chomp!
Shake~!
After landing a strong bite, Akui didn't let go before shaking Kaneki around destroying more of their surroundings.
Blast!
Boom!
Before letting out a powerful blast whilst still holding onto Kaneki.
But even that.
Chomp!
Wrap!
Didn't stopped Kaneki.
He bit onto Akui in retaliation before wrapping his body around Akui.
Roll~!
Akui: AAAAAARGH!
Crash!
After securing a tight grip, Kaneki preformed a Death roll sending them both crashing back to the ground.
Back in the Stadium*
???: Woah! Just how strong is this guy?!
???: Is this the strength of a Demon Knight?
Everyone who was watching in the Stadium were caught in awe, the fact that the Battle between the two Kaneki's was able to affect the real world despite being inside someone's soul.
Itsuki: That Kaneki made of those flames is seriously scary!
Keiko: which one? They're both made out of flames.
Itsuki: The Black one.
Keiko: Oh yeah, that one destroyed the other Kaneki's like they were nothing.
Natsuki: Haa~ thank goodness Kaneki wasn't completely destroyed.
Sachi: Yeah. Just how much stress will Kaneki out us through? I'm so going to beat him up later for that.
Chikao: I wonder when this fight will end.
Natsuki: I think Kaneki's fight with himself will end soon.
Sachi & Chikao: let's hope so.
Meanwhile*
Miku: This will be the last Battle between Onii-chan and himself right?
Yuuka: Yeah. Let's just hope he can win over that Kaneki.
Shino: Go for it Kaneki!
Back in Ryueki city*
Kaneki: are you done with your tantrum?
Akui: JUST DIE ALREADY!
Blast!
Akui: I just want it all to end! JUST LET ME END THIS NIGHTMARE!
Slam!
Akui began acting erratically, he started hitting his head on the ground.
Kaneki: I see... In that case.
Swoosh!
Kaneki then came right in front of him and then.
Boom!
He untransformed from his Dragon form and back to the form he took prior.
Kaneki: ...
Akui: ?!?!
After seeing himself right in front of him.
Akui: ACCEPT OUR FATE AND DIE!
SWOOSH!
Akui opened his mouth wide open intending to destroy him by devouring him.
But before he could do anything.
Akui: !!!
"Kaneki!"
He saw his friends and family in front of him, and immediately stopped.
Akui: Haa~! Haa~!
After stopping he immediately got frustrated and started lashing out.
Akui: Why?! Why can't you just let me end our nightmare?! What's the point in us living if we're only going to cause pain to everyone! We're nothing but a murderer! We don't deserve to live!
Kaneki: I understand how you feel, yes we are responsible for Mom's death because we didn't listen to her. But... Everyone who came after wasn't in our control, but we tried to save them remember?
Akui: NOT SAVING THEM IS THE SAME AS MURDERING THEM!
Kaneki: what kind of thinking is that? ... Then again.
Step!
Kaneki then approached Akui.
Touch*
And touched one of his teeth made out of his flames.
Kaneki: you're still a scared and confused kid.
Burst!
Upon making contact, Akui had untransformed from his Dragon form and turned back to flames with no physical body.
Kaneki: You've done enough, you don't need to kill yourself.
Akui: I do! I won't let anyone be sad because of me-
Kaneki: By killing yourself? erasing our friends and family's memories? If you do that you'll only be alone.
Akui: ...
Kaneki: it's alright, you don't need to do that.
After hearing that, Akui replied with a whimpering voice.
Akui: I have to, to pay for my crimes. Besides they hate me.
Kaneki: no they don't, stop lying to yourself.
Akui: but-
Kaneki then asked with a smile.
Kaneki: c'mon, you want to back too don't you? You want to continue playing games, cook, eat tasty food and have fun right?
Akui: I don't-
Kaneki: that's not for you to decide, c'mon. We're done with revenge, we we can go back to them now.
Akui: but they'll hate us...
Kaneki then tilted his head and asked.
Kaneki: do you not trust your friends and family? What makes you think that? Sure they'd be mad but they were reaching out to us, I'm sure even you can hear them as well.
Akui: ... Will they still accept me? Even after everything I've done?
Akui asked with his eyes made out of red flames staring into Kaneki.
Kaneki: there's only one way to find out.
Kaneki made a hand out of his flames, and reached out to Akui.
Kaneki: let's find out together, shall we? If I can forgive you then everyone else can too right?
Akui: even after destroying myself and trying to erase myself... All for revenge... yet you...
Seeing Kaneki forgive and accept him, Akui reached out with his own hand.
Grip!
And touched Kaneki's hand.
Swoosh!
And his Black and Dark Red flames died revealing, Kaneki when he was 3 years old.
Kaneki: good, let's go have some fun. Then let's go back to our friends, okay?
Akui: okay.
Burst!
Swoosh!
Akui's flames suddenly reignited, and went into Kaneki's own flames and mixed together with him and the other Kaneki's.
And upon mixing together with the other Kaneki's.
They all began talking to each other.
Kaneki 0: hey so you finally decided to give up huh?
Akui: I don't know, I still hate myself.
Azuna: Hehe~ don't worry you're not alone on that one me! I still hate myself for letting this all happened. It may not look like it but it's true.
Quan: and we still hate ourselves for hurting our friends.
Shitsuren, Tomo & Kozo: that's right.
Azuna: but we still have to live on, not just for our own sake but for our heroes too! They've saved us countless of times. We still haven't repayed them yet.
Kaneki 6: We can't let our friends get hurt anymore, right? So we have to get stronger.
Kaneki 7, 8 & 9: let's just hope they can still accept us even after everything we done.
Kaneki 10: let's face everyone head on, no more running.
Kaneki 0: That's right! Let's tell them everything, they'll understand.
Akui: ...
Seeing his other selves willing to face their friends, Akui felt the same way.
Akui: Yeah... They will.
With Akui agreeing with them.
Kaneki 0: Good! Let's do this then!
Azuna: Everyone! Let's have some fun!
All 10: YEAH!
With all 12 Kaneki's now together. Kaneki's Battle against himself has ended.
"Looks like Kaneki has won his battle against himself!"
As this was announced.
Natsuki: KANEKI KICK THAT GUY'S ASS! AND RIP HIM TO SHREDS!
Natsuki was cheering for Kaneki like there was no tomorrow.
Kaneki: Now then, shall we have some fun?
With Kaneki's Battle against himself now over, his battle with Ryueki will now continue once again.
