Kamiya Karen

The little step-sister of Yato. She's currently in the 3rd year of middle school.

Appearance
Karen is a very beautiful girl and because of that very popular with the boys.

Personality
Karen has the air of a cold beauty. She loves her brother dearly (romantically) and gets jealous and annoyed when other girls try to approach him romantically.

She feels very secure in being with Yato and often tries to get close to him while covering up the reason. Although, there are moments where Karen doesn't hide her feelings, e.g. going into his bed at night and snuggling up to him while thanking him for all the times he's saved her.

History
Karen's parents adopted Yato a long time ago after he lost his parents in an accident. She'd been bullied by a couple of girls in primary school. It stopped with the intervention of her brother.

She doesn't seem to have any friends in her middle school and is despised by some of the girls there out of jealousy because of her huge popularity among the boys due to her beauty. She often gets love confessions, but rejects them all, saying that she already has someone she loves.
