In Deep Space, many different cultures have come together to live on the planet Jet. To maintain peace, an organization known as the Jetters is formed. This space police group fights against the villains known as the "Hige hige dan," ensuring that the universe remains safe. The leader of the Jetters, Mighty, is a powerful Bomberman who is looked up to and respected... his brother, however, is a lazy, crude slacker named Shirobon. Suddenly, Mighty disappears, and Shiro finds himself placed in a new situation. Shiro steps up and becomes a responsible Bomberman, and with the new friends he has made among the Jetters, it may become possible for him to be the next "Jetters leader."
