Tengu no Daidokoro

On, a boy from New York, discovers he is a descendant of a tengu. According to their traditions, after reaching 14 he must spend a year of seclusion in Japan with his older brother, Motoi Izuna. Tengu aren't particularly powerful; they live a simple life working in the fields and enjoy cooking, which only disappoints On. His interest only gets caught after discovering his brother has wings! Will he also develop tengu powers?!
