Subaru Ichinose loves his cockpit as, to him, it's like being in his mother's womb. Whenever he struggles to converse with his fellow pilots, his cockpit is the one place he can be alone. As the ace pilot aboard the Tiramisu, Earth Union's most important battleship, it is his job to defend Mother Earth from the threats that emerge from humanity's extended dominion spreading throughout the vast reaches of the universe. Armed with his personal mecha Durandal, Subaru must fend off encroaching foreign colonies as he struggles to protect his personal sanctuary from rogue fried pork skewers, suffocating backwards shirts, and unsolicited redecorations. In the year Space Age 0156, the fate of humanity rests entirely in his hands.

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.

It is the year 2201. The Yamato has returned from the devastating battle with Emperor Zordar and the Comet Empire. Sanada, Aihara, and Shima are released from the hospital, and go to pay their respects to the fallen crew members at Okita's memorial. They meet Tokugawa's son Tasuke, who says that he will be joining the crew once he graduates from cadet school. The next day at his graduation, he ends up capsizing a boat full of new cadets because they are all too busy staring at the Yamato to watch where they are going. After some problems during launch due to the new engine crew hitting the wrong switches and stalling the ship, the Yamato departs on what should be a simple training mission. (Source: AniDB)
