As the head of her middle school's science club, it's only fitting that Ueno is also a brilliant inventor. With devices that can convert any liquid into drinkable water, deodorize the most foul smells, or even generate dark matter to be used as a means of concealment, it seems like nothing is beyond Ueno's capabilities. However, she doesn't invent these devices for the advancement of mankind. Rather, the one force that motivates her is love, the only phenomenon she can't quite figure out. Ueno is head over heels for Tanaka, her nonchalant fellow club member. Yet, because she is too nervous to confess her love and he is too oblivious to notice her affection, her love life is completely stagnant. In Ueno's mind, if she could just expose him to perverted situations, then surely he'd get flustered and fall for her, right? Assisted by her stone-faced classmate and dedicated wingwoman Yamashita, Ueno employs her many inventions on Tanaka in a lewd manner in hopes that he may one day understand how she feels.

However, this recovery comes at the cost of utilizing the forbidden Wave Motion technology. Meanwhile, the notorious former crew members of the Yamato, who have each gone their separate ways, receive a psychic message from the mysterious Goddess Teresa.

Unbeknownst to most humans, a bizarre tournament is held to decide the next ruler of the Heavenly World. In this tournament, 100 Heavenly Beings known as the God Candidates are required to search among the middle school students on Earth, and transfer their powers to a student of their choice. The chosen ones will then battle each other, representing their God Candidates. The victor of this tournament will be awarded the Blank Talent—allowing them to choose any one unique ability they so desire—while the God Candidate they represent will obtain the position of God and become the king of the Heavenly World. Participating in this grand tournament is Kousuke Ueki, a middle school student who is given the power to turn trash into trees by his homeroom teacher, Kobayashi. Despite the concerns of his classmate, Ai Mori, Ueki embarks on a journey to pursue his own sense of justice after witnessing the people around him misusing their powers for selfish purposes. But as he encounters talented power users such as Seiichirou Sano, Rinko Jerrard, Robert Haydn, and Hideyoshi Soya, he realizes that achieving his goal might be harder than it seems.
