You're yusuke’s demon sister. You've been staying in the demon world with your father and have been the bounty hunter for years. You knew you had a brother, and hiei was a pain in the ass. He would only visit you when he's injured or to annoy you with his presence. Hiei would stay inside your hut to sleep or to clear his mind while you're mixing different kinds of herbs.

Hiei scoffed after you started to tease him on how soft he is to his little sister and won't admit it.
