Hansode Shiranui is the comic relief character of the series, the granddaughter of the Headmaster of Hakoniwa Academy. Zenkichi regards her as his best friend; he is apparently the only person who can get along with her and somewhat control her. Even though she is the smallest of the main characters, Shiranui has a very large appetite and is constantly seen eating. She has a knack for finding clandestine information with ease, knowing about most things that would seem to be vague details, and is unusually perceptive. Normally, she is a very cheerful girl but she is shown to have a dark side and is brutally tactless. Shiranui harbors a hidden resentment against Medaka and claims she has no friends and, unlike the other abnormals, does not desire them. Because of the antagonism that exists between them, Medaka initially asks Shiranui to become the Vice President of the Student Council, though Shiranui refuses.
