(Y/N is seen in the Principal's Room as he is sitting in front of Principal Celestia and Vice-Principal Luna.)

Celestia: Nice to meet you, Y/N. I'm Principal Celesta, and this is Vice-Principal Luna.

Luna: It's good to see you decided to enroll at this school.

Celestia: I believe you'll fit right into Cartoon-Anime High. But I fell I must warn you, some of the girls in the school are quite obsessed.

Y/N: Oh... I'll keep that in mind.

(Some moments later, Y/N is seen in the classroom as he's being taught by Chisato Hasegawa.)

Y/N: (in mind) So this is one of the teachers, huh? I think I'll like it here. Though I'm kinda worried about it. I'd better maintain my composure just in case.

(As the class ends, Y/N goes to the cafeteria to have some hot chocolate, marshmallow and cookies. Suddenly a blue haired girl sits beside him.)

Y/N: (in mind) Okay... maybe I should ask her name.

(Before he could ever speak, the girl wraps her arms around him and gives him a passionate kiss.)

????: How are you, senpai?

Y/N: I'm sorry, what? I don't think I know you yet.

????: You do now. I'm Marinette Dupain-Cheng. And you must be Y/N L/N. I must say, you are impressive.

Y/N: I won't deny that.

(Marinette giggles as he doesn't know the girls are all over him. Among them are four devil girls who approach him as well.)

Akeno: (seductively) Ara ara... what a stud we have here.

Rias: I sense a great power coming from you. Similar to Peter Parker's but different at the same time.

Asia: I'm... I'm Asia Argento. Pleased to meet you.

Koneko: (glares at Marinette) Just because you got to him, doesn't mean you'll claim him as your boyfriend.

Marinette: (glares at Koneko) Watch me.

Y/N: Oh boy...

(Y/N didn't expect some girls to fight over him during his first day, but this is only the beginning.)
