Japan’s post-apocalyptic wasteland replete with dust can only be saved by one thing—fungus. Bisco Akaboshi, a wanted criminal and skilled archer, searches for a legendary mushroom, known as Sabikui, said to devour any and all rust. Joining him on this epic saga to save the country is a giant crab and a young doctor. Can this unlikely trio find the fabled fungi and save the land?
