The Law of Ueki, Vol. 2 (Law of Ueki (Graphic Novels))

Ueki begins to face off against opponents in this deadly tournament, but will his environmentally friendly ability hold up against more lethal powers like changing water into flames and changing towels into iron? Then Ueki discovers that there's a reward for winning the whole tournament--you get any power of your choice, but the penalties involved in this game could be more than he bargained for.
