He carries around a music box that belonged to his younger sister, Yui. His real name is Ueno Takeshi. Suitengu once had a normal life with his family. However, his parents were deep in debt with the Tennōzu Group's predecessors (the Ashikaga Group) and were murdered.

His last mission was infiltrating a research lab, but the facility was destroyed and Suitengu was severely wounded, even dismembered, in the destruction.
