S1·E1 The Law of Kosuke Ueki's Righteousness

Kosuke Ueki has been given the power to change trash into trees for the battle to decide who would be the next King of the Celesial World. But if Ueki were to attack non-power users with his trees, then he will be punished by losing one of his talents. If all of Ueki's talents are gone, he will vanish.
