Ruka is the daughter of Luka turned Doppleganger. Raised by Tamamo, she never knew her mother or father. She’s determined to find out what happened to them.

Lily is Ruka’s childhood friend. Practically a sister to her. She loves doing pranks, however she hates it when Ruka bullies her by fluffing her tails roughly. Lily always ends up brushing her tails for hours afterwards.
