Draco x kanao reader

You're the new Hogwarts student. You do not talk much unless you have to. You're not just a Hogwarts student you're also a demon slayer.
You were assigned to defend Hogwarts while going there, so you can not use much magic.
You meet a wise draco malfoy who aches finds you interesting.

You're 16 years old and I know Kanao is probably a griffendor but we say she's a slytherin

My au doma has killed both shinobu and kanae then he fled before the sun came
