The immediate sequel to Heisei Shin OniOni Shima: Zenpen, released simultaneously with the first part. The two games are based on the popular Japanese fairy tale about the "peach boy" Momotaro. He was found by an old man inside a huge peach, and when he grew up, he swore to slay the evil demons and to take their treasure. On his way to the demon land, he met three animals: a dog, a monkey, and a pheasant, who helped him on his quest. The second game is split into two parts: the first tells the story of the pheasant Ohana and the princess Otohime, while the second is about the ultimate battle of the heroes against the evil.
