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.

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)

2199 AD. Yamato tried to leave behind the Large Magellanic Cloud galaxy, after receiving a Cosmo Reverse System at its destination, Iscandar. However, suddenly, it encounters a mysterious group at the edge of the Large Magellanic Cloud. The crew finds out that the group is called the Gatlantis, and that its leader is the Gutaba expeditionary force commander who calls himself Goran Dagaamu of Thunder. The commander demands that Yamato be handed over to him. Yamato, wanting to hurry to Earth, escapes the fray. However, Yamato is attacked by a devastating beam weapon called the Flame Direct Attack Cannon that can transcend space. Yamato was able to retreat, but ends up getting lost, and finds itself in a strangely colored irregular dimension. The crew decides to turn off the engine on the ship, and explore a mysterious planet. In order to collect information, Kodai, Kiryū, Sawamura, Niimi, and Aihara land on the planet. What they saw when they arrived was a ship that was not supposed to be there. Dagaamu chases after the traces of Yamato's warp, and also reaches the strangely colored space. The planet on which Yamato landed was in fact what Dagaamu had been looking for all along. (Source: ANN)
