In the far future, a disaster known as the "Rusty Wind" has
transformed the majority of
Japan into a barren desert and left civilization
in tatters. After his teacher falls prey to
the rust, the roguish Bisco
Akahoshi embarks on journey through the sandy wastes to
obtain a mushroom
known only as the Rust Eater, rumored to cure the ailment.
Together with the
dashing young doctor Milo, the pair will have to contend with the
environment and their fellow wanderers in order to make it back alive.
