Swoosh!
Shatter!
Kotori: You can't escape Onee-chan, cute little brother~ Hahahaha!
Kaneki: Onee-chan is having too much fun!
Punch!
Wrap!
Chomp!
After Kotori had revealed her ability to copy Kaneki's own powers and abilities, with these copied abilities capable of temporarily disabling his own powers.
Kaneki: Tentacle Arts, Kraken Style!
He was testing both himself and Kotori.
Kaneki's thoughts*
(So even getting touched does the same thing too huh?)
He was rather curious to what extent his weakness can go for.
Slash!
Splatter!
Kaneki: Argh!
Kick!
Crash!
All while he was getting thrown around and beaten badly by his older sister who didn't stopped her attacks even for a second.
But even so.
Kotori: You're still smiling after receiving a beating huh? Don't worry I won't be stopping!
Kaneki continued to smile through everything.
In the Stadium*
???: Woah he's actually getting beaten up.
???: Kotori-san looks so creepy with that grin.
???: Higanbana-kun seems to be enjoying it though.
Everyone watched Kaneki getting thrown everywhere by Kotori.
Splatter~!
And his blood covering huge areas around Fake Shimotsuki.
Keiko: This really bad, Kaneki might actually lose!
Itsuki: What she said is true, Kaneki had a horrible match up.
Sachi: I can't believe Kaneki's actually getting beaten up by Kotori Ai-chan!
Even Itsuki, Keiko and Sachu were all worried about him as well.
Natsuki: Don't think he's going to lose yet.
Miku: That's right, This is Onii-chan after all.
But the rest of the Higanbana girls weren't.
Chikao: Have you forgotten Sachi? Kaneki is pretty smart sometimes.
Yuuka: and he is probably studying Kotori-san right now.
Sachi: what do you mean?
Yuuka: it's pretty obvious isn't it? Look.
Natsuki pointed to the Jumbotron, and the feed of the battle continued.
"C'mon! Is that all you got Onee-chan?! Ora!"
Crack!
Pierce!
Kaneki was pierced by a tree that sprouted out of Kotori's arm as she copied Kaneki's Dryad Arts.
Steam~
"I knew it! There's limits to what you can do!"
Yuuka: Kaneki was studying her, he remember this is the same guy who made made plans to catch Miku's bully.
Natsuki: Yeah. Kaneki's smart so he's definitely thinking of something.
Sachi: I sure hope whatever he's planning it would work.
Back in Fake Shimotsuki*
Kotori's thoughts*
(Kaneki-chan is studying me, he's definitely formulating a plan to take me down. I'll just have to defeat him before he does.)
Kotori already caught on Kaneki studying her so she was going to defeat him before he could think of a plan.
Kaneki: Darkness Travel.
Splash!
Kaneki created a ball of black goo behind him using Darkness Travel, seeming like he was trying to get away.
Splash!
Kotori: I'm not letting you get away!
Kotori created her own puddle and went through.
Kotori: Huh?!
But as she passed through the other side, Kaneki's puddle was present but he didn't passed through.
Kotori immediately realized what happened.
Kotori: Did I just get baited?!
At Kaneki*
Kaneki: good I lost her, well then.
Splash!
Splash!
Vroom~!
Kaneki reached out his hand into the puddle and pulled out the Grand Chain-sword that Kirari gave him.
Kaneki: Alright, it's time! Demonic portal!
Vroom~!
Swoosh!
Slash!
Tear~!
With a powerful swing he created an air slash that created a huge demonic portal in the sky.
Kaneki: Let's do this.
Warp!
Kotori: Akuma Castle?!
In the Stadium*
Yuuka: What?! Why did he bring Akuma Castle?
Chikao: I know it has defences but would that even be enough?
Natsuki: Maybe he's going to absorb more of those memories?
The sudden appearance of Akuma Castle surprised everyone and the Higanbana girls wondered what Kaneki is planning to do with it.
Shino: Whatever it is, I have a weird feeling this is going to be big.
Miku: same here.
Natsuki & Sachi: Most definitely!
In Fake Shimotsuki*
Kaneki: active defences.
Thunder~!
Zap~!
After entering Akuma Castle, Kaneki immediately commanded it to activate it's defences.
After doing so lightning began to be rapidly shot out of it, creating a barrier.
Kotori: Come out Kaneki-chan! You can't hide in there forever!
Crack!
ROOOOOAAAAR!
Blast!
Beam!
Bang!
Boom!
After seeing Kaneki go into Akuma Castle, Kotori used the abilities she copied from Kaneki to attack Akuma Castle, this includes the Yurei, Shino and Shin Dragons.
Shake~!
Kaneki: Woah~! This is not going to last, I have to do that Akuma Castle hold on a bit longer!
Kaneki made his way through Akuma Castle until he reached the throne room.
Kaneki: here it is!
He went behind the throne and opened up a panel that was hidden.
Kaneki: Thank goodness it's in Japanese!
Press!
He frantically pressed many buttons, but not randomly he was putting in passcodes.
Kaneki: Just a bit more! And!
"Akuma Castle's voice is now active, ready to serve current master"
After finishing the last passcode, Akuma Castle was able to speak.
1 hour before the Battle, in the Infinite armory*
Kaneki's thoughts*
(Good most of everything is no done, all I need now is to use Akuma Castle)
When Kaneki finished most of his preparing for his battle with Kotori, he wanted to use Akuma Castle as well.
He knew there was more to Akuma Castle than just it being a base.
Kaneki: Akuma Castle, upload memories of Demon Knight Tesla. Memories that hold information about Akuma Castle.
So he decided to look into the memories of it's creator in order to understand what it could do.
And he found many things previously unknown about it.
Kaneki: Haha~! This is going to be awesome!
Flashback end*
Kaneki: Nice to meet you-
"I was already active before the activation of my voice, there is no need for introductions. Master Omega"
Kaneki: Oh okay, but please address me by my actual name please. It's Kaneki Higanbana.
"Affirmative Master Kaneki"
Kaneki: Well... We'll work on that, you're already aware of what's going on right?
"Correct, do you want Akuma Castle to use it's full power?"
Kaneki: Yes please.
Spring!
Kaneki: Woah!
Suddenly a strange mechanism that have mechanical arms sprung down from the ceiling.
It seemed like Kaneki was needed to wear it.
Kaneki: so I just need to?
"Correct please enter the cockpit, the controls will automatically attached itself to you"
Kaneki: Okay.
Step!
Swoosh!
Kaneki: Woah!
As Kaneki walked closer to the controls they immediately attached themselves to him.
Shake~!
Kaneki: Hey what's happening?!
And as the controls attached themselves, Akuma Castle.
Begun to transform.
