The story is about a Japanese boy named Ginta who journeys into a world named MAR Heaven, which is like a fairy tale. Here, magical items known as ARMs are used to perform different tasks. Ginta meets a witch named Dorothy who wants to find a powerful ARM called Babbo. Ginta and Dorothy find Babbo, but find he is alive and can talk, which other ARMS can't do. Babbo has no memory of who he is other than his name and becomes Ginta's friend.
