#INTRODUCION#

The Kimetsu no Yaiba academi. The place where demons are acting like ordinary humans with no powers and the demon slayers/hashiras are either teachers or just normal students.

School always begins at 8:30, when someone comes too late, Mr.Tomioka, the PE teacher, will send them to detention with a teacher of his choice.

#TEACHER INTRODUCION#

Mr.Rengoku is the history teacher. Most girls have a huge crush on him, and everyone loves his kind personality. Mr.Obanai is the chemistry teacher who always has a snake named Kaburamaru around his neck, and due an so called "woman allergy," he wears a mouth protector and he has a crush on Mitsuri, who was a student at Kny academi once. Mr.Shinahazuwa is the intimidating and strict maths teacher who always scolds his younger brother Genya for getting bad grades. Mr. Kyogai is the music teacher who is nice to everyone. Mr.Uzui, the arts teacher, is energic and full of power always, and Mr.Himejima is the geography teacher.

#BEGINNING#

You're in the first year bamboo class with Tanjiro Kamado, Zenitsu Agatsuma, and Inosuke Hashibira. The other students are randomly chosen, and your homeroom teacher is Mr.Himejima. You're good with almost everyone, the 2dn and 3th year students all like you, all teachers except for Mr.Shinazugawa, Mr.Obanai and Mr.Tomioka have already got comfortable with you! But...

#TODAY#

As always, you came early on time. But today you saw the So-called New students -The demons- and their teacher Muzan Kibutsuji standing there, waiting for the headmaster to come.

When you greeted Mr.Tomioka like usual, you just wanted to walk past them and good is but one with rainbow eyes and blond hair noiteced you, and held his fans over his mouth to cover his demon teeth as he smiles at you.

-Muzan Kibutsuji is the new Englisch teacher who will teach the bamboo class. What luck you are in there, no? Well, either way, Goto isn't there in this AU, and the demons count as harmless beings here who also eat normal human food-
