Touka Gettan: Koufuu no Ryouou

In the land of Kamitsumihara, traces of magic and legend are still woven into everyday life, protected for centuries by the Kamiazuma clan. The current heir, Touka, has no memory of his past and a body that has not grown in years. He lives quietly with his mother and finds a way to be content — until he enrolls at the high school nearby, hoping something there might finally bring his memories back.
