Let me fight with you

After completing his Mother's challenge, Kaneki 0 was about to devour the fruit of power.

Until he heard the cries of his other selves, due to this ht thought he wasn't ready to attain such power yet.

So he had hidden it and lied about destroying it to his other selves. This action made them go berserk.

Prompting him run towards Ryueki and opened him in half creating a portal to somewhere ball 11 Kaneki's to freely rampage.

And now.

Kaneki 0: Wow this place is annoying to look at.

Kaneki found himself in a place that looked like a city... With golden statues of Ryueki all over the city.

Natsuki: Ew! My worst nightmare!

Natsuki was disgusted upon seeing where Kaneki was in through the Jumbotron.

Natsuki: I think I'm going to vomit.

(Author: Me too Natsuki, Me too.)

Itsuki: Wait where is Kaneki anyways?

Sachi: Yeah, is he in another world or something?

Chikao: Did Kaneki get isekai'd?

Querxes and Kirin: not exactly.

All 5: Querxes and Kirin Sensei?!

Kirin: Yo, sorry we've been absent for a while.

Querxes: we had important matters regarding to Kaneki to attend to, but well looks like Kaneki is able to use one of the Demon Knights secret abilities.

All 5: secret ability?!

Querxes: correct, the ability to go into another persons soul.

Kirin: you kids have seen this with Tohru earlier.

Natsuki: Wait... You two knew about Kaneki being a Demon Knight?!

Querxes & Kirin: correct.

Querxes: we'll explain the rest later, let's just continue watching.

They then turned back to the Jumbotron.

Crash!

Kaneki 0: oh there they are!

The other Kaneki's have arrived.

All 9: RAAAAAAAAAAAAAH!

and they were all going berserk.

Swoosh!

Kanekin0: Crap!

Kick!

Crack!

Kaneki 0: ARGH!

Kaneki 6 flew and kicked 0 with his talons and kicked with incredible force.

Kaneki 0: Ora!

Vroom!

As Kaneki 0 was about to swing the Grand Chain-sword.

Bang!

Kaneki 0: ARGH!

Burst!

Kaneki 0 was shot on the hand and he lost his grip on the Grand Chain-sword, and upon letting go the Chain-sword returned to where it was prior.

"What the heck? Why am I back to before? No I'm way slower than before... Unless?! No way! "

In that moment, Kaneki 0 realized why he was very weak.

"It's fatigued isn't it?!"

Since Kaneki's main body hasn't rested since the previous day and was up all night he was weaken quite a bit.

But with the addition of him making his wish, summoning his other selves, getting beaten until his regeneration no longer worked and his power getting absorbed to grow the tree.

The fatigue has now completely caught up with him.

Slash!

Kaneki 0: tch!

Clang!

Chomp!

Kaneki 0: ARGH!

"Are you kidding me?! Am I seriously going to be ripped apart again?!"

Kaneki was more pissed than worried about losing.

Yuuka: seriously?! Is he going to lose because of fatigue?!

Shino: Hang on Kaneki!

Miku: Fight while you sleep!

The Higanbana girls were concerned about Kaneki's fatigue.

Sachi: Kaneki's going to lose because of fatigue?! Kaneki fight while you sleep!

Chikao: are kidding me?! Fight in your sleep.

Natsuki: Kaneki go fight while you sleep!

They were even suggesting him to fight in his sleep.

Crack!

Kaneki: ARGHHH!

"Even if I wanted to fight while sleeping I'll just be woken right up!"

Kaneki knew there was no possible way for him to fight while sleeping.

Chomp!

Rip!

Pierce!

Bang!

Kaneki 0 was getting hit by countless attacks and he wasn't able to dodge or tank any of the hits.

Kaneki 0: Bleurgh!

He was receiving so much damage.

"Crap! This is bad!"

Tohru: [Kaneki-chan!!]

All 9: Die!

When the other Kaneki's were about to land their strongest attacks.

Blast!

All 9: AAAAAAAAAH!

Kaneki 0: Haha~ took you long enough... Ku-kun.

Ku-kun appeared and blasted them far away.

Ku-kun: Geez, I was hoping you would call out saying "someone please help me!".

Kaneki 0: sorry, I wasn't sure if it was really you that I was smelling.

Ku-kun: good thing I was in the drone over there.

Ku-kun looked at the drone that he rode in.

Kaneki 0: hehe~ so you rode in there huh?

Ku-kun: Anyways. WHAT THE HECK IS WRONG WITH YOU KANEKI! DID YOU SERIOUSLY TRY TO KILL YOURSELF AND LEAVE ME ALL ALONE?!

Ku-kun immediately scolded Kaneki as he was both pissed and sad for what he had done.

Ku-kun: I'D BE ALL ALONE IF YOU DISAPPEARED KANEKI! TAKE RESPONSIBILITY!

Kaneki: ... Yeah... I will and... I'm really sorry, Ku-kun.

Ku-kun: An apology is not enough! Let me fight with you!

Kaneki was a bit worried at first since Ku-kun, isn't much experienced in fighting.

Kaneki: are you sure? You haven't really been into any real battle's so it may hurt.

Ku-kun: I'm your familiar Kaneki, if you're in trouble I'll help!

But seeing his determination to help him reassured him.

Kaneki 0: Hehe~ thanks.

All 9: RAAAAAAAAAAAAAH! KU-KUN! GET AWAY FROM HIM!

As the other Kaneki's got up, Ku-kun was eady to fight.

Ku-kun: rest up Kaneki, I'll fight them for you.

Kaneki 0: 3 minutes, that's how long you have to fight them until I'm fully rested.

Ku-kun: good in that case, let's fuse.

After hearing Ku-kun's request to fuse.

Kaneki 0: fine with me.

Kaneki agreed to it.

Ku-kun: Finally! I've been waiting for this moment for so long! I'm so happy!

Ku-kun was instantly overjoyed upon hearing Kaneki agreeing to fuse with him

Ku-kun: GYUGIGIGIIIIIII!

Swoosh!

Kaneki 0: Woah!

Ku-kun grown to the size of a small car and flew directly to the other Kaneki's.

All 9: ARGH!

Crash!

And knocking them down before flying back to Kaneki.

Kaneki 0: have some fun, Ku-kun.

Crash!

Ku-kun flew straight in to Kaneki.

Splash!

Swoosh!

Upon hitting Kaneki, Ku-kun's body became a red goo that covered Kaneki's entire body, and what seemed to be Ku-kun's soul passed through him.

Ku-kun: here I go!

All 9: NOOOOO!

Swoosh!

Ku-kun's soul then flew back towards Kaneki's body.

Ku-kun: Change Stag Beatle!

Chomp!

Upon reaching the body, Ku-kun's soul chomped on Kaneki's body before being absorbed by it.

BOOM!

And then a new form was born.

Itsuki & Keiko:Woah!

All 6: Kaneki/Onii-chan and Ku-kun looks amazing!

???: What is that?!

???: amazing!

Ryueki: Tch!

Everyone was amazed and surprise upon witnessing the birth of a new form.

Ku-kun: Woah! We look so cool!

"Yeah we really do look good"

The new form they took was of a Knight, their entire body was more muscular and covered with a tough red armor that came from Ku-kun.

And two swords in the shape of Ku-kun's Mandibles.

A simple yet cool design.

Ku-kun: alright Kaneki, rest well and leave it to me for the time being.

"3 minutes, please don't push yourself too much Ku-kun"

Ku-kun: Heh! You're not the one to talk, BAAAKA!

"Well then, good luck"

Ku-kun: see you in 3 minutes partner.

After saying this, Kaneki went to take a 3 minute nap and, Ku-kun was now in complete control of Kaneki's body.

All 9: Why... Why did you have to make Ku-kun suffer too!

Ku-kun: I'm your familiar! If you suffer I'll suffer with you!

And he was more than ready to face the other Kaneki's.

Swoosh!

Ku-kun: Bring it on!

In an instant, Ku-kun went in front of the other Kaneki's and urging them to attack.

All 9: Ku-kun get out of here!

Ku-kun: Heck no!

Punch!

Grab!

Thwack!

Slash!

One of the Kaneki's tried punching Ku-kun, but he was able to catch it and punch him before taking one of his swords and slashing it at him.

All 9: Ku-kun!

Ku-kun: Heh! Catch me if you can!

Swoosh!

All 9: You're not getting away!

Ku-kun then started running very fast around the city with all the other berserk Kaneki's chasing after him.

Swoosh!

Kaneki 6: AAAAAAH!

Ku-kun: Hip!

Kaneki 6 flew straight to Ku-kun, in which Ku-kun immediately made a backflip and.

Ku-kun: Ora!

Kick!

Kicked him to the ground.

Ku-kun: Heh! Hmm?

Swoosh!

Slash!

Quan: Get back here you!

Tomo: I'm just doing what's best for you!

Quan and Tomo came to slash and bash Ku-kun from two sides.

Grip!

But he grabbed both Scythe and Shield.

Ku-ku: YOU DON'T KNOW CRAP!

Crack!

The back of the armor opened up and unfolded two massive wings.

Buzzz~!

Spin!

Crash!

Using his wings, Ku-kun spun very quickly sending Quan and Tomo flying.

Swoosh!

Bang!

Ku-kun: Oh my you missed, hit me if you can!

Ku-kun taunted Kaneki 10.

Bang! Bang! Bang!

Kaneki 10 then started shooting a lot more bullets.

Swoosh!

Crack!

Ku-kun: Homing Bullets?! Now that's fun!

After noticing that the bullet were homing bullets.

Ku-kun ran very quickly, dodging the homing bullets and making them hit the surroundings in Ryueki City.

Through the streets, Statue's and even walls.

Ku-kun: Heh! I lost them!

All 9: think again!

Ku-kun: !!!

While running away from the bullets by running to the top of a building on the walls, Ku-kun was ambushed by a 10 other Kaneki's

Slash!

Bang!

Blast!

They sent out their strongest attacks and upon hitting, it caused an explosion.

And as the dust settled.

All 9: !!!

Ku-kun had disappeared.

Ku-kun: Yo did you guys get him?

All 9: !!!

He then appeared on the far right side of the building sitting with his legs crossed.

Ku-kun: Kuwagata Blast!

Beam!

Boom!

And shot them all with a powerful beam of light.

Itsuki: Woah Ku-kun is good.

Keiko: Yeah he's really fast! And he's even able to use Kaneki's body with ease!

Sachi: Wow, even though it's his first time fusing with Kaneki and he's in control.

Chikao: I guess those two are really compatible with each other.

Natsuki: Yeah and I'm glad Kaneki's relaying a bit on Ku-kun now.

Kaneki's friends and the Higanbana girls were amazed to see how Ku-kun was managing Kaneki's body with ease.

Yuuma: Woah I didn't expect this.

Shino: well I guess this makes sense, since our 5 insect familiars Ku-kun is quite literally the strongest.

Miku: yeah, a very fitting partner for Onii-chan.

But then...

Sachi: I wonder where Miracle has gone off to? Wait a minute how long has it been since their switch?

Natsuki, Chikao, Itsuki & Keiko: !!!

Querxes: Just in time.

3 minutes had already passed.

Ku-kun: Alright Kaneki, let's fight together now!

Kaneki 0: I'M FULL OF ENERGYYYYY!

With Kaneki 0 now rested.

Kaneki 0: Oi! Azuna let's settle the score already!

He now challenges his Demon Half, Azuna.

Azuna: ...emoC
