A first year in high school, Misaki is close friends with Meguru and Yuu, as well as the next door neighbor and childhood friend of the Zaitsu brothers. Misaki ("Saki" for short) is a teenaged girl who is rather tall for her age (she ranks as among the three tallest of the female characters) and is notable for having a well-developed and busty physique (one reason why she is ogled over by Kusuda). She has a very open relationship with her neighbors, and even comes into Mamoru's room through his window, and is the only character in the series who's not afraid of Misao (in fact she often has casual conversations with him). She somehow knows and is very proficient in submission techniques, and can perform them instinctively in her sleep; in the anime, she was seen executing some on a hesitant Misao to get some answers out of him. She even has a penchant for loudly declaring the name of her wrestling moves as she performs them. In the manga, she is revealed to be a K-1 fan. Though she claimed she had no interest in relationships at the moment, she developed an interest for Yuuji Arihara when he shoved a lollipop in her mouth (showing an example to his friend, Yoshihiko Bessho). But although she likes Yuuji, she is not used to feeling vulnerable around boys, because she's usually cool and level headed. When Yuuji begins to express his interest in her (In the same way she did to him), it makes her shy and unsettled, so she tells Arihara to leave her alone. He later explains that love is about letting people see your other sides as well, not just your tough side. They seem to be dating after the series end. It was also revealed that being an only child, she's quite envious at those who have siblings, and thus, as part of her attraction to Yuuji, she also takes a liking to his younger sister Ayumi, treating her as a younger sister of her own.
