Kosuke Ueki has been given the power to change trash into trees for the battle to decide who would be the next King of the Celesial World. But if Ueki were to attack non-power users with his trees, then he will be punished by losing one of his talents. If all of Ueki's talents are gone, he will vanish.

Mori has decided to help Ueki, but she’s starting to see threats in every direction. When any middle school student could be a gifted, who knows when Ueki will be challenged. Two gifted do cross their paths. One is Seiichiro Sano, a decent type who they met while trying to rescue a small girl from a big fall. Another is Maruo Taira, a less than decent individual who has no problem attacking from behind. With the ability to turn water in his mouth to fire (and a little help from his God Candidate), how will Ueki fair in his first official gifted fight?

Thanks to Seiichiro Sano, Ueki defeats Taira. As Sano leaves, he talks about the Talent of Blank… Afterwards, Ueki and his school's running team practice with another school's running team. However, Ueki is soon lured into a trap by Adachi, who can turn cotton into stakes.

Mori is determined to learn more about this tournament so when the opportunity arrives to gain such information from Mr. K, she leaps at the chance. During their talks they are interrupted by another gifted. Unlike Ueki’s previous opponents, though, this one is different. Li Ho prefers to use his own body to fight rather than his given ability. When Li Ho starts smashing Ueki’s trees with his bare hands, not even the sarcastic talent can help our hero. So what can he do when Li Ho unleashes his most powerful attack: The Count of Monte Cristo?

With another win and another zai under his belt, Ueki is able to relax for a little bit. When traveling by train one day, he meets Junichi Baba a.k.a. B.J., a hip-hop enthusiast who takes an immediate liking to Ueki. So why does he also say his name is Robert Haydn when he discovers that Ueki is also a gifted? Fortunately, B.J.'s ability to turn coins into wind is not enough to stop Ueki. The two part on friendly terms, but when the real Robert Haydn shows up, what will happen to Ueki’s new friend?

Mr. K sacrifices himself to save Ueki from certain death.

Ueki finds out why Mr. K was so interested in him. Ueki also gets a new God Candidate, Yodogawa (AKA Yotchan), who wants him to drop out of the battle. Ueki fights his next opponent, Bolo T, who can turn his forehead into a diamond.

Ueki's next opponent is Onimon (full name - Oniyama Monjirou), who can turn the dirt he kicks into cannon balls. This guy is different from all the other guys, and it's not because he likes to shorten names.

The fight between Ueki and Onimon reaches its conclusion. A week afterwards, Onimon trains Ueki so that Ueki can fight a stronger enemy known as Kuro Kage, one member of Robert Haydn's Ten.

Ueki continues his fight against Kuro Kage, whose sad past is told by Kuro Kage's little brother.

Ueki's fight with Kuro Kage comes to an abrupt end when Kamui Rosso (a.k.a. Shiro Kage) takes out Kuro Kage. Ueki defeats Shiro Kage and is then asked to join Robert's Ten. For some reason, Ueki accepts.

Robert has Ueki peform an entry test for him to pass if Ueki wants to join the Ten. Ueki then picks a fight with one of Robert's Ten, Allegio Yuriano. Mr. K discovers the truth about Ueki and Robert.

A large Heavenly Beast appears during the fight between Ueki and Aleggio. Ueki learns more about his potential powers as a Heavenly Being from the Beast, who befriends Ueki.

Ueki tells the rest of Robert's Ten (except Robert himself) that he defeated Aleggio. As a result, the Ten's Don decides to fight Ueki. Using his power to change his finger ring into a rocket, Don soundly defeats Ueki. In order to get stronger, Tenka has Ueki train in the Awakening Organ so that Ueki can raise his Heavenly-Being rank.

Now a 4-star Heavenly being, Ueki easily defeats Don in their rematch. Word about this gets out to the rest of Robert's Ten, including Marco Mardini and Rinko Jerad, whose sad past is revealed.

Ueki's exhaustion finally catches up with him. So, Tenko places Ueki in a Healing Chamber. Ueki will have to tay in the chamber to heal for 12 hours. While Ueki heals, Tenko and Rinko must fend off the remaining members of Robert's Ten, Oni, Becky Wolf, and Myoujin Tarou.

Ueki battles Myoujin, the last of Robert's Ten. Myoujin uses his two powers to overwhelm Ueki.

Ueki recieves an invitation to a "party" held by Robert Haydn. So, Ueki, Rinko, Inumaru and Mori all go to an arcade that leads to Robert's underground theme park called Dogura Mansion. There, Ueki fights in the first round against Yun-Pao, one of the new members of Robert's Ten.

Ueki continues his battle with Yun-Pao, still trying to figure out Yun-Pao's limit. Later, in the next fight, Mori finds herself battling on the Cossack Field against Kabara, a member of Robert's 10 and a notorious hunter known in the underworld.

It's Rinko vs. Kabara, and they fight in the...cat field? The objective is to get the opponent to get eaten by a cat, and to do that, they have to turn into a mouse! Slap the cat's nose and they become a mouse! Kabara seems to have the advantage in this one thanks to his ability to fly, but Rinko has a few tricks up her sleeves: some new weapons and a...love of animals?

Ueki battles against Sano on the Rope-Jumping Field. The real reason why Sano joined Robert's Ten is revealed.

Sano joined the ten for a very specific reason: to rescue Inumaru from a devious attack by Karl Paccho. Using a Death Pentagon, an insect that can instantly kill a heavenly being, Karl forced Sano to join or watch his God Candidate die. But Inumaru's sense of justice won't stand for these conditions. He breaks the cardinal rule of this tournament: a God Candidate can only grant powers to one individual. When he gives Mori powers of her own, he is instantly sent to Hell, freeing Sano of the Ten's grasp. Of course this only serves to infuriate Ueki even more. With a challenge made to Karl Paccho, a new fight begins. But Karl has a surprise: his talent is to copy the power of other gifted. With all the power of Robert's Ten at his disposal, Ueki is in for a tough fight.

Ueki continues his fight with Karlpaccho, who has more tricks up his sleeve. An event from Robert Haydn's past is revealed.

After Robert's past is revealed, Ueki begins his battle against Robert.

The battle between Ueki and Robert reaches its climax!
