Nobuyuki

2199 AD. Yamato tried to leave behind the great Magellan system, after receiving a “Cosmo Reverse System” at his destination, Iskandal. However, suddenly, he encounters a mysterious group at the edge of the Magellan system. He finds out that they are called the “Gatlantis,” and that their leader is the Gutaba expedition group’s governor-general who calls himself “Goran Dagam of the Thunder,” and the governor-general demands that Yamato be handed over to him. Yamato, wanting to hurry to Earth, escapes the fray. However, Yamato is attacked by a vicious beam weapon called the “Flame Direct Attack Cannon” that can transcend space.

Yamato was able to retreat within a hair’s breadth, but ends up getting himself lost, and finds himself in a strangely-colored irregular dimension. He decides to turn off the engine on the ship, and explore the mysterious planet. In order to collect information, Kodai, Kirio, Sawamura, Niima, and Aihara also arrive at the planet. What they saw when they arrived was a ship that wasn’t supposed to be there.
