Reiko Ichinose

Reiko is Kais mother. She works as a prostitute. In the manga: She likes the sea a lot but she has never seen it so she named Kai after the name of sea. She was born and raised at the Edge of the Forest so no wonder she became a prostitute. She hates her work and guys too. She gave birth to Kai when she was 15 so in the beginning of the manga she is 25. She looks really young.
