The single daughter of the high school's principal, who, on the outside, behaves well like a rich man's daughter. On the inside, she is revealed to be quite sadistic and threatens Kinjiro on his greatest fear and using his gynophobia to make him suffer. She is shown to enjoy tormenting and teasing Kinjiro by using his gynophobia against him. However, she did give thoughts about finding a way to cure his gynophobia although her methods to do so are generally overly complicated or humilate him in some way and she does not deny that she finds them amusing. She notes that Kinjiro is the first, and only, man who is willing to talk her down and she is implied to have fallen in love with him as a result.
