The Law of Ueki

Ueki is just an ordinary junior high student-until he’s given the bizarre ability to turn trash into trees. The mysterious Mr. K grants him this power but drags him into the "Battle of Supernatural Powers," a deadly tournament with 100 fighters. If Ueki wins, Mr. K will take the throne of the Celestial World, and Ueki will earn the "Talent of Blank," letting him pick any power he wants. But if he racks up too many penalties along the way, he’ll vanish completely. Now the fate of the world hinges on this unassuming kid and his strange new gift.
