## Plot

The story starts out with the Battle of the Supernatural Powers, a tournament to decide which Celestial (heavenly being in the original Japanese version) will be the next King of the Celestial World (God in the Japanese version).
Each of the 100 King Candidates (God Candidates in the Japanese version) is required to choose a junior high school student to act as their power user. The student is given a unique power and told to eliminate as many enemies as possible. The winning King Candidate will become the new King of the Celestial World and the winning student will receive the Blank Talent (Black Zai in the Japanese version), a talent that can be anything they choose.
While this leads many students to thoughts of greed and selfishness, Kosuke Ueki decides to take it upon himself to win this tournament to keep that power away from those that would abuse such a gift.

### The Law of Ueki Plus

Two years after the tournament in The Law of Ueki, Kosuke Ueki is now a 3rd year student in Hinokuni Junior High School. For some reason, everyone in the real world has lost their memory of their most important person, including his friends who participated in the tournament two years ago. Ueki is the only one unaffected, and is fighting in order to restore everyone's memories. He follows a little sheep named U-lu to another world called Hangekai where he meets new companions and gains new abilities.

## Reception
### Manga

Luke Carroll of Anime News Network ranked the first volume as B−. Carroll lauded the concept of Ueki's power to turn trash into trees and the humor of the series, but called it "another run of the mill shounen title". He labeled Fukuchi's art style as "simple" and compared it to One Piece, as "there is vagueness in a lot of detail", but clarified that it is suited to the comedic tone of the story. Michael Aronson of Manga Life ranked the first volume as C+. He criticized the series for its similar premise to other action manga series and for its "overly hyperactive" characters. Aronson concluded; "fans of hyper action series like One Piece and Dragon Ball will feel at home here. Anyone else will merely glaze over and out." Patti Martinson of Sequential Tart gave a 4/10 for the fourth volume. Martinson compared the content of the volume to the anime adaptation, and wrote; "at times the manga made less sense than the DVD did. However, the characterizations seem to be slightly better, but not enough to make me see what happens in the next volume."

### Anime

Carlo Santos from Anime News Network criticized the series for its "run-of-the-mill" plot and "ridiculous" characters, calling them "underdeveloped", but stated that the series is "[b]izarre and crazy enough to be entertaining at times". Santos also criticized its "sloppy" artwork, repetitive fights and the English dub, concluding: "Like its titular hero, The Law of Ueki seems energetic and full of promise, but right now lacks the necessary self-control to succeed." Chris Beveridge of AnimeOnDVD commented that the series "is a real hard sell", commenting that the characters are hard to connect with, the pacing of the first episodes is very fast and its plot is "something that we've seen in its most base form a million times now". Beveridge also criticized the series' artwork, which blends traditional and digital animation, calling it "disconnected at times" and that it makes it look like an "unfinished show". Jeremy Mullin of IGN compared the premise of the series to Zatch Bell! and commented that the powers of the characters are similar to those from Fullmetal Alchemist, "with the conversion factor involved", highlighting as well the variety of ways in which they are used. Mullin concluded: "The Law of Ueki was something I was interested in checking out, and it seems to be worth it. It's full of some good ol' fashioned anime craziness with some positive messages thrown in for good measure."
