Marina Sugisaki

Marina Sugisaki is the mother of Miku and Ryuuta. She usually appears with a smile on her face and acts rather incompetent. Frequently, she embarrasses Miku with her odd interests such as "safariing", and cataloging unusual children in her daughter's class. She is most interested in Marui Mitsuba due to the girl's sadistic and brash attitude, so Marina's submissive behavior naturally attracted her. Mitsuba, on the other hand, is creeped out by the clingy behavior. Marina offers many invitations to the Marui triplets to visit and offers gifts to Mitsuba, she is part of the reason for the eventual friendship between her daughter and the triplets.
