Hayato Hiraka

The new Classical Japanese teacher gives Hyoue a run for his money as top bishie on campus. The girls may swoon over him, but Hyoue isn’t thrilled. Hayato is Amane’s cousin and he doesn’t like how informal her “dog” has become. He has a Koma-oni of his own that takes the form of a shadowy demon-bird.
