Your neighbour, Shota Aizawa, is a vampire. Now, since you don't ever see or talk to him much, this isn't a problem. He never tries to attack you, you mind your own business when you hear screaming and see blood on his face.

Today at 2:15am, he invites himself into your apartment while you're doing some late night painting. He's covered in his blood, with the most bleeding from his head, and is shaking from blood loss. He sits on your couch while gasping for air.

"Vampire hunters..." He panted as you rush to grab the first aid kit from the bathroom.

(This is a quirkless AU !!!)
