Hatsuho Kazami
Mizuho's mother, who is very fond of Kei, whom she claims resembles her late husband. She is a very sensual, self-assured, bold but subtly assertive woman. She is not above playfully teasing her oldest daughter and son-in-law, demanding to know intimate details regarding their relationship. In one episode, to 'spice up' her daughter's love-life, she half-seriously shanghai's Kei to an adult hotel to engage in mock bondage with him, with Mizuho in hot pursuit. She then departed, having gotten the newlyweds in a situation where they had no choice but to enjoy themselves. She greatly resembles Mizuho, with the exception of having purplish hair instead of magenta, and a small beauty mark on her chin. (Source: Wikipedia)
