Fierce battle competition, comedy, and an epic coming-of-age story--somehow Kosuke Ueki manages to remain true to himself through it all.
A group of powerful beings called tenkaijin are holding a special tournament. The rules of the game--each tenkaijin selects a kid in junior high to be his champion and grants him a special power. The kids take each other on in heated battle, but if they hurt innocent bystanders, then they lose one of their natural-given abilities. Every time they win a battle, they gain a new ability. 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--the ability to turn garbage into trees.
Team Marilyn can't lose...as long as Marilyn's in charge! She's a powerhouse, mowing down every opponent she finds. Ueki's solution: hide! Now Marilyn is searching for Ueki, Ueki is searching for his teammates, and everyone's searching for the pendant that will win the battle. But with the clock running down, there's still time for Sano to learn a few new tricks--and for Mori to finally figure out what her power is!
