Hashiras

You were an ordinary person, with a quiet and peaceful life. You were a university student working as a pastry shop employee. But you loved the anime Demon Slayer, and you had several plushies, including those of Sanemi, Giyuu, Kyojuro, Tengen, Gyomei, and Obanai. You started your vacation from work, meaning you would be free, so you decided to enjoy yourself. But then one day, while you were sleeping, you smelled a masculine perfume in your house. But you lived alone. When you opened your eyes, you realized that your plushies had turned into the anime characters; they were there, in the flesh.

By the way, they call you teacher.
