*Okko the ronin heads a small group of demon hunters roaming the empire of Pajan. In his company are Noburo, the enigmatic giant who hides his face behind a red mask; Noshin, the whimsical monk and sake lover with the power to summon and commune with the spirits of nature; and last but not least, the young fisherman Tikku, who has become a member of the group in his own right, and whom Noshin teaches the secrets of his art.
Summoned to the bedside of a girl tormented by a demon, Okko revisits traces of his past in a village where blood was once spilled. As bad omens proliferate, they must confront the son of a man he killed long ago and save the life of Noburo, who has become the quarry of a fearsome and legendary demon hunter. *Source: Okko: The Cycle of Air #1
