The Law of Ueki is an anime television series directed by Hiroshi Watanabe, animated and produced by Studio Deen. The series is based on the manga series of the same name, by Tsubasa Fukuchi. A total of 51 episodes were broadcast by TV Tokyo. Geneon Entertainment picked up the series and broadcast the English dubbed version.
Mori has decided to help Ueki, but realizes there are other competitors challenging him. Two power users cross their paths. One is Seiichiro Sano, a decent type, with the ability to turn towels into steel, whom they met while trying to rescue a small girl from a fall. Another is Mauro Taira, a less than decent individual, who has no problem attacking from behind. He has the ability to turn water in his mouth into fire. Ueki notices that he can make trees into any type he wants, this time using a chestnut tree so the chestnuts on fire can purposely hit Mauro and burn him (although he wanted to eat them).
