Toudou Koyori

Koyori 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.
