Ruruu Aki Kajuta

Ururu's sister by a different mother. She was born from an affair with another woman and raised by Gen. Because of this, she intends (but doesn't really want to) to kill Hime. However, she is constitutionally incapable of hurting him, so she seeks a way to kill him painlessly (resulting in a rather peculiar choice of method). Like all members of the dragon race, she worships Ururu as her idol.
