Querxes and his student were supposed to spar but their sparring session only lasted around 10 minutes because Kaneki stopped moving.
???: Huh?! what happened?
he stopped moving.
???: he looks really messed up. look at those tentacles.
Yuuka: wait a minute! look at his arms! their black.
Mitsuha: no way Higanbana-kun demonized.
everyone: demonized?
Mitsuha: demonization is an ability of demons and half human half demons have but it's really difficult to do.
???: Really! that probably means he's so happy he's not able to move.
Itsuki: no wait look!
at the battle*
Querxes: Hey Kaneki?
Kaneki: N
Querxes: What?
Kaneki: No, No Noooo! i don't want this! don't you Dare! Demonize! i won't let this happen!
Kaneki started to panic.
Kaneki: Why! Why! why are you demonizing you piece of crap!
???: What's going on he was just enjoying himself earlier.
Natsuki: (his colors are being tainted again by Rage and sadness!)
Shino: (No! this can't be happening why? why are you calling yourself that!?)
Miku: (Onii-chan what's wrong?)
Yuuka: ( this is worse than i thought)
at the battle*
Kaneki: don't you dare Demonize you couldn't even protect them! you don't deserve this demonic power! I hate you!
Kaneki started saying he doesn't deserve his demonic power.
Kaneki: SENSEI~ OUR SPARRING ENDS NOW IM GOING HOME~
And Kaneki wanted to go home.
Querxes:... take this then *throws a small object* Pudding your favorite get home and cool down.
Kaneki: I'm outta here.
Swoosh*
Kaneki left immediately without a trace.
Chikao: Hey Preston-san!
Querxes: what?
Chikao came to Querxes.
Chikao: what happened to him!? and why did he say he didn't deserve his demonic power and why did he say he hates himself?
Querxes: oh Yuri-chan Kaneki told me about you a long time ago, well I can't really say why but like he said earlier "you couldn't even protect them!" he has regrets that are linked to his demonic power.
everyone was stunned to hear that.
???: i wonder what's wrong with him?
Ryueki: he's probably just thought he couldn't protect his imaginary friends.
Natsuki: now is not the time for that.
Miku: Mizutani-san are you worried about him?
Natsuki: not really but somehow I saw myself in him.
everyone was silent and then.
Querxes: well I guess I have to do this. FORGET EVERYTHING YOU SAW AT MY AND KANEKI'S BATTLE!
Querxes used one of his abilities to make almost everyone forget seeing the battle and what happened.
Itsuki: huh? where's Kaneki?
Querxes: oh he left 3 minutes ago, he went home and he beat me in our quick sparring session.
Chikao: seriously~ i wanted to see him fight!
Querxes: well I'm outta here too. we'll all meet again but till that time comes see you guys later.
swoosh*
Everyone was confused because almost all of them had their memories erased except for 4.
Shino: didn't I tell you guys we shouldn't have gone here (what happened? he actually made everyone forget!)
1st Miku
Miku: know what I'm heading home too. see ya guys.
Yuuka & Shino: bye!
Ryueki: see ya later.
Querxes-san made everyone forget what happened and also i must see how Onii-chan is doing!
2nd Yuuka
Yuuka: hey Natsuki wanna go shopping?
Natsuki: S-Sure.
Ryueki: since when were you two friends?
Yuuka: since yesterday, anyways Natsuki let's go! (i wonder if Natsuki didn't get affected by that)
3rd Natsuki
Natsuki: let's... go. ( Querxes-sans colors. they show protectiveness towards Kaneki-kun if that's the case i understand why he erased everyone's memories.)
4th Shino
Ryueki: I'm heading home now, see you guys later.
Shino: see you later Itadori-kun.( why? why was he in so much pain earlier? and Querxes.. he erased everyone's memories... so he could protect Kaneki? ... i can't, seeing his face like that is so painful he's in pain all because of us three! we must make things right!)
what will these 3 and Natsuki do now?
Shino, Yuuka, Miku & Natsuki: (I must save him from his pain)
