Katou Mamiko

Akari and Matsuri's mother. She is in her 40's but still looks young enough to be in her late 30's. Her breast aren't as large as Akari's but they are bigger than Matsuri's.
While she has something of a flashy sense to her she has never been with any other man aside from her husband. When she finds out her husband has been going to cabaret clubs she leaves home to stay with Akari for awhile.
