???: Sorry we had been very rude to you in the past, Higanbana-kun I hope you can forgive us.
After Kaneki had reassured all of the female students of his school, he was confronted by his female classmates who didn't really do anything wrong against him or his friends during the W.S.S.F.
Kaneki: It's alright everyone, besides non of you did nothing wrong so I can look pass your past behavior. I just hope non of ya ate punishment slop yet.
???: Phew~ good thing we decided to not participate in that challenge yet.
Kaneki: You all better go to your seats now then, class will begin soon.
His female classmates then went back to their seats after he had told them to.
Sachi: Hehe~ looks like our classmates were very decent people huh?
Kaneki: Yeah, I'm quite glad they didn't attacked you guys or I probably would've force fed them punishment slop.
Sachi: Haha...
Creak~!
Querxes entered the room with a couple of books in his arms.
Chikao: All Stand up~
Everyone: Good morning Sensei!
Querxes: Good now take your seats.
After they all took their seats and with a smile, Querxes began to praise his students.
Querxes: Well done everyone, you all did very well in the W.S.S.F and our undefeated champion of the W.S.S.F Kaneki. Give him a round of applause.
Clap! Clap! Clap!
Everyone in the room began to clap their hands for Kaneki.
Kaneki: C'mon guys please stop.
Querxes: Now in other news next week we were supposed to have an exam but because of everyone in Mato High's great performance in the W.S.S.F. it was decided that we'll postpone it until further notice.
Keita: Woohoo!
Yuta: Awesome!
???: Thank goodness!
???: No Exam!
Everyone was quite happy with the exam being postponed.
Sachi: This is so great! We don't need to study too much now.
Keiko: Yeah this is great.
Querxes: And beg we start our activities I have one more very announcement to tell you all.
Miku: Hmm? An important announcement?
Yuuka: What could it be?
Querxes continued to smile and then looked at the door.
Querxes: You can come in now.
Slam!
Everyone: !!!
Kotori: Hello everyone~!
Kotori came into the room very quickly and almost broke the door as she slammed it open.
Everyone: Kotori Ai?!
Sachi: Ehhhh?!
Everyone was very surprised upon seeing her join their class.
Querxes: From this day forwards, Kaneki's older sister Higanbana Kotori Ai will be part of our class.
Kaneki: I didn't expect you to join our class, Onee-chan.
Sachi: Wait Kaneki you knew Ai-chan would be applying for our school?
Kaneki: Aiya Mama and Papa told me after I got home from lunch the other day, although they told me to keep it a secret.
Kotori: Hehe~! I'll be in everyone's care from now on.
Natsuki: Welcome to our class Kotori-san.
Chikao: Let's get along.
Kotori: Likewise! Now Sensei where do I take my seat?
Querxes: Over there, that seat is empty.
Querxes pointed to an empty seat but as Kotori looked at it, her expression grew dark.
???: Eh? What's with her?
???: Doesn't she look kind of pissed?
The reason for this was simple, it was because that empty seat belonged to the one who brought pain to her precious brother and friends. Ryueki Itadori.
Kotori: Everyone near that empty seat, I request for all of you to move away for a bit. I also advise you all move your seats out of the way for the time being.
???: Umm... Why do you-
Kotori: Just do it.
Kotori said very coldly.
Rumble~
Obeying her words, everyone who sat near Ryueki's table and chair all moved away with their seats.
Kotori: This thing was sat on by that piece of trash, anything that is connected to it shall be incinerated.
Crack!
Four metallic tentacles grew out of Kotori's back at aimed at Ryueki's table.
Kaneki: Disappear from my sight.
Burst!
She began to shoot out concentrated flames from these tentacles aiming at Ryueki's seat.
She also put up a barrier so no one would get hurt and nothing else gets damaged.
In mere seconds the entire seat was disposed of, only leaving melted metal behind.
Kotori: Alright then.
Snap!
Poof!
And with a snap of her fingers a new chair had appeared out of thin air and what's left of Ryueki's old seat disappeared.
Once she had destroyed Ryueki's seat and replaced it for one that she created using a copied power of creation from Kaneki.
Kotori smiled and said.
Kotori: Alright that's done, everyone can put their seats back to where they belong.
???: Wow Ai-san seems to really hate Itadori.
???: I mean he did almost got Kaneki killed so it's quite obvious why she hates him.
Everyone in the room besides for Kaneki and the Higanbana girls were all a little afraid of Kotori after her action against Ryueki's seat.
Upon realizing that she had messed up.
Kotori: Wait I made a bad first impression!
She to panicked.
Kotori: Now everyone is going to be afraid of me and I won't be able to make any friends~
She sulked thinking she had ruined her chance to make new friends.
???: It's alright Higanbana-san.
???: Yeah we kind of understand why you did it.
???: Just calm down okay?
But to her surprise her classmates were very understanding of her actions since they knew why she acted that way.
Itsuki: Yeah you don't really need to worry about first impressions, besides if Kaneki can make new friends despite doing some crazy things, so can you.
Kaneki: Yeah Onee-chan no need to sulk.
Seeing how she was already accepted despite her behavior Kotori felt very happy.
Kotori: Thank goodness!
Querxes: Alright then take your seats now, we're about to begin.
Everyone: Okay.
Kotori: Let's begin!
Kotori happily sat on her seats as their class started.
A few hours later~ Lunch time*
Kaneki: Mmmh~ this is so good.
Since Ryueki is no longer a around Mato High, Kaneki and the Higanbana girls no longer needs to have lunch together in secret.
They put their seats together and ate lunch together in their classroom.
Miku: Here this Tako Hotdog is so cute.
Natsuki: Thanks Miku.
Sachi: Mmmh~!
Chikao: Hehe~
Shino: Our next class will be P.e right?
Yuuka: Yeah I think so, I wonder what we'll do later?
With no more worries about Ryueki, they all are lunch happily with almost everyone in their class watching them.
???: I wonder how long those guys have been having lunch together?
???: Probably a long time right? We never really see them during lunch time when Itadori was here.
???: That actually makes a lot of sense.
But as they were eating lunch.
Meanwhile~
Kotori: Hmm~♪ Hmm~♪ Hmm~♪
Kotori was walking through the halls of Mato High with a smile on her face.
Normally she would be shown around the school by one of her classmates, but she decided to go look around on her own.
Kirin: Oh hey Kotori.
While walking she ran into Kirin.
Kotori: Hello sensei~
Kirin: you look happy, how are you adjusting to school life.
Kotori: Good! My classmates were very accepting of me and their very kind.
Kirin: I'm happy to hear that.
Kotori: By the way are you taking being a Sensei as your full time job? I mean your original purpose for becoming a Sensei here as well as Querxes Sensei was just to watch over Kaneki-chan.
Kirin: That might be true, but I've grown fond of the students in this school. I mean compared to Kaneki everyone here is very tame.
Kotori: Haha~ fair point.
Kirin: Speaking of Kaneki, how is he holding up? With him discovering that he's a Demon Knight I am a bit worried.
Kotori: It's alright, he doesn't really care much about it.
Kirin: Good well then, you better go eat lunch. If you didn't bring anything to eat with you go to the Cafeteria, just go straight and when you see the infirmary go to the hallway to the left and go straight again and you'll reach the Cafeteria.
Kotori: Thanks! I'll be on my way now.
A few minutes later~
???: Wow that's a lot.
???: Who would have thought Kotori Ai was such a glutton?
After arriving at the Cafeteria Kotori had ordered a lot of food, so much that she created a tower of food almost 3 meters tall.
Kotori: Itadakimasu~!
Though there were many students staring at her, she didn't care and started eating happily.
As she was eating
???: Umm...
She was approached by a female student from a different class, not knowing what she was up to Kotori offered some of her food.
Kotori: Hmm? You want some?
???: N-No I'm good, um...
Swoosh!
The girl suddenly pulled a tiny book out and bowed while holding it in front of her.
???: C-Can I please have your Autograph?! I'm a huge fan of yours.
Kotori: Oh a fan? Nice to meet you then, here.
She then took the book and wrote her name on it.
Kotori: It's a pleasure to meet my fans, so? Is that all you want? I'm free to talk if you want to.
???: Y-Yes!
And so Kotori talked to this female student while eating lunch until lunch time was over.
40 Minutes later~
Kotori: Hehe~ that was fun.
Kaneki: Did you made a new friend?
Kotori: Yup, I met a fan of mine and we talked during lunch. It was fun.
Sachi: That's good to hear Ai-chan. You're doing quite well.
Kotori: That's right! Not only I was able to ace our test earlier, I was able to make a new friend!
Kotori was very proud of the progress she made in her first day of School.
But the real struggle was about to begin.
Querxes: Alright everyone, we're going to have P.e class so you all need to go change into your school swim suits.
Kotori: Eh? How come?
Querxes: Today's P.E class will be held at the pool for swimming lessons
Kotori could do many things but, there is one thing she is unable to do and that.
Splash!
Kotori: Crap.
Was swimming.
