Misaki Yamamoto

As a high school freshman and longtime childhood friend of the Zaitsu family, this energetic neighbor shares an incredibly close bond with her neighbors. Her familiarity with Mamoru is so deep that she frequently enters his room uninvited through the window. Beyond her playful presence, she possesses a mysterious, instinctive mastery of various submission techniques, demonstrating a surprising level of physical skill that seems to manifest even while she is fast asleep.
