Nuts

Nuts is an orphaned youth living in 'Orshima,' a downtown area of Ikihama City. Amid a post-apocalyptic world plagued by the threat of rust, he demonstrates remarkable drive in order to protect those around him. Initially, he had planned to capture Akaboshi Bisco in exchange for a bounty to fund defensive weapons, but after coming to understand Bisco's true convictions, he changed course and became a vital source of support for Bisco and Milo's activities in the region.
