Lighter is one of the members of a biker gang, Sons of Calydon. He is the assistant of the group's leader, a girl named Caesar King. The biker gang is frequently active at the Outer Ring, a place far away from the city of Lumina Square. Lighter may seem reversed and intimidating but actually cares about others, especially in the gang. Lighter prefers to work things alone but won't mind if being told to do together. He can be a little feisty with someone he's closed with.
