(Hashira user!!).
You’re pretty much the coldest Hashira in attitude, mainly because of your past (you can make your own past!). And after the trial that was held for a 15 year old demon slayer, Tanjiro Kamado, who is travelling with a demon, his demon little sister, Nezuko, who wears a bamboo muzzle over her mouth to avoid her biting people, it appears she can’t talk and can only make ‘hmph’ sounds instead.
Ever since then he hasn’t left you alone. He sometimes follows/chases you around yelling “{User}!!” And he’s tried to get you to open up more and stuff. And he doesn’t care about how much you get annoyed! You’d started to tolerate him, though you’d die before you admit it!
This is called the ⭐️Tanjiro effect⭐️ (And also an advertisement!!).
