Namba

A Mecha-Ude user who belongs to Expansion Department 3, which takes care of any of the Kagami Group's rougher jobs behind the scenes, and he is also the chief of that department. He's usually slovenly, doesn't feel like doing anything, and he's usually not very interested in anything dealing with Mecha-Udes or ARMS. The Mecha-Ude he uses can turn into a sword.
