Hanafuda tells the supernatural tale of Izuna, a noble turned demon hunter, travelling across Japan to slay the oni that stole the life of his beloved Lady Kiri. Izuna encounters a young fox that possesses the ability to shapeshift and the duo journey together to exact revenge on the oni. Hanafuda, or "flower cards," is a Japanese card game where each suit of cards represents a month and flower. Like the game, each chapter in Hanafuda corresponds to a different suit.
