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.

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.

With his scientist father occupied with research, he can only rely on his childhood friend, Kotori Izumi, the popular and good-natured daughter of his father's employer. At the end of their third year of high school with graduation right around the corner, Shin and Kotori finally begin to move forward together, both in life and in love.
