Shun Asanaga, a bright and optimistic 15-year-old junior high school student, stumbles upon a mysterious crystal in the office of his father—a scientist and businessman. When he touches it, reality warps and he is transported to the world of Endra. Emilio, a prince of Endra, is approaching his 16th birthday and resents the current king, Delzain. Now old enough to inherit the throne, Emilio arms himself and seeks revenge, but his weakness leads to his capture and imprisonment by Delzain. As Emilio grieves in his cell, the wall distorts and Shun appears, arriving with two objectives: return to his own world and fulfill Emilio's revenge. What lies ahead for the two boys, raised in different worlds yet forced to survive together in Endra?
