Taiko no Tatsujin: V Version

Don and Katsu are brothers cleaning the house when they find a mysterious book they do not recognize. Before they can investigate it, the book pulls them both in and deposits them in a strange world where two moons hang in the sky. A large dragon attacks almost immediately. A girl named Maple fights it off with them and explains: it was a "Noise Devil," one of many evil beings that have been devastating villages throughout this world. Don and Katsu offer to help, and Maple accepts. Their journey to stop the Noise Devils begins.
