Kanade Suzutsuki

Age: 16-17
Height: 168 cm (5'6")

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 Kinjirou on his greatest fear and using his gynophobia to make him suffer. She is shown to enjoy tormenting and teasing Kinjirou 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 Kinjirou 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.

In Volume 10 of the light novel, Masamune tells Kanade that they are very much similar, and that Kanade can't trust anyone else, that she puts up a facade. This leads to Kanade having several revelations and confessing to Jirou, despite knowing that Konoe also loved Jirou. This leads to Kanade, Masamune, and Konoe all fighting for Jirou's affection.
