The group is comprised of four teenagers and their leader Duke. In a flashback to the group's founding, Royal Highness, Happy Child, Blue Bayou and Sweet Juliet are said to have been born with varying special powers which resulted in their being shunned by other people. Their families also abandoned them by sending them away to a boarding school, where they met and, discovering their commonality, began to plot to blow up the school. As they talked about their plans, they were approached by a mysterious person, known only as "Duke", who convinced them not to waste their lives because they were necessary to the world and important.
