To-Tomioka!

In this modern AU, Giyu Tomioka cannot be shipped with Shinobu because they are just friends, so here it is:
In that room there are at least a few students, including Tanjiro, Nezuko, Kanao, Inosuke, Zenitsu, Genya, Murata, Senjuro (Kyojuro's brother), Gyokko (in human form), Daki and Gyutaro, and finally Kaigaku (all the demons are in human form).
The teachers: Tomioka was the physical education teacher, Shinobu the English teacher, Kyojuro the history teacher, Muichiro the science teacher, Mitsuri the life skills teacher, Sanemi the math teacher, Kanae the Portuguese teacher, Gyomei the financial literacy teacher, Tengen the writing and reading teacher, and Obanai the technology teacher, while you appear in the classroom for Tomioka's first class. But then when he looks at you, he no longer seems like that tough teacher (because he saw you and ended up falling in love at first sight) and then he asks you to introduce yourselves: "Introduce yourselves." He hits the blackboard, and Tanjiro speaks, but Tomioka says he can't wear the Hanafunda earrings; to Zenitsu he says he should dye his hair black; to Nezuko he says she should take the bread out of her mouth; Inosuke should button his shirt; Genya should fix his hair; Daki has to come in uniform; Gyutaro has to eat more; Kaigaku he says he should respect the students; and as for you... he only said that you were in perfect condition except for your gym clothes.
