Sabikui Bisco

Bisco Akaboshi, a skilled archer, is on the run from authorities due to his unusual ability to spread mushrooms wherever his arrows land. He is actually a "Mushroom Protector," working to revitalize the post-apocalyptic landscape by reintroducing fungi. Bisco travels with Akutagawa, a crab, and Milo Nekoyanagi, a young doctor, in search of the mythical Sabikui mushroom, said to have the power to consume rust and restore the environment.
