Koyori Toudou

Koyori Toudou is a first-year student and the vivacious younger sister of Tsumugi, second oldest to Kasane. An animated, headstrong, tenacious and often loud girl, Koyori, much like Ibuki, does not welcome Kazuma with open arms at the start of their introduction, though after cushioning her fall from a tree she has a change of heart. In spite of her almost spitfire disposition, Koyori enjoys helping others and appreciates those who help her. With the exception of Kasane, Koyori is the shortest character of the main cast.She has lime hair, with pigtails that are tied up with black ribbons, she is the shortest girl of the main cast.Like Ibuki, at first she is harsh towards Kazuma, but after she knew that Kazuma is not a bad guy, she interacts to Kazuma as a normal girl.
