A warrior named Sword encounters a mysterious girl who asks him to explore an old clock tower. As he arrives there, he is attacked by a heavily armored enemy. Pursuing the assailant, Sword finds a strange book and opens it. Everything changes, and the hero is teleported into another dimension. It appears that several other heroes beside him were lost in this dimension, each coming from a different world. Sword 's task is to locate these heroes and find a way to bring them back to their respective worlds.
Combat requires precise positioning of the characters in order to execute attacks and capture monsters. A peculiar feature of the game is the reversion of the characters' level to 1 upon completing a dungeon. The characters retain the items and the skills they have learned, but start again at the lowest level in the next dungeon.
