Tsukamoto Kaori

Ririsu's mother. Kaori is the owner of a youthful appearance, young enough to pass through as Ririsu's older sister. She usually has a mild temperament, but she tends to show motherly playfulness towards Ririsu. She also appears to be a crying drunk.

In Memo Off 6: T-Wave (In this game she made a voice only appearance):
She is living with Yuugo (the dating itself has started a few years ago). This relationship has caused a major conflict between Kaori and Ririsu, making the later move in with her grandmother Fumiko, and away from her mother.

In Memo Off 6: Next Relation:
The relationships conflict between the parents and the children of the two families (Yuugo and Shio, Kaori and Ririsu) has been already settled. They are all living together in peace.
