About Law of Ueki

A group of powerful beings called tenkaijin are holding a special tournament. Each tenkaijin selects a kid in junior high to be his champion and grants him a special power. The ultimate winner of the tournament is granted any power of his choosing, and the tenkajin who he represents succeeds in becoming the next god. Kosuke Ueki has been chosen to fight in the tournament. His special power is the ability to turn garbage into trees.
