Ryo Yajima, 34, comes from Gifu. She is a full-time housewife with two children. She has a great figure, with a height of 170 cm and a G-cup bust, but she is actually a black belt in Shorinji Kempo with 14 years of experience! When she changes into a karate uniform and shows off her favorite kicks, they are so powerful that they send the weak and timid man flying! However, Ryo, who is kind and caring towards this weak and timid man, is a wife full of maternal love who is devoted to her husband and loves herbivore men. Although Ryo is like a Ryo, her problem is that her husband is too herbivore and doesn't pay her any attention.
