Using the warp gate, the Yamato must bypass the planet Balun. But they’ll have to punch through a massive Gamilan fleet if they want to arrive at the Large Magellanic Cloud in one piece.

The Gamilans set their ambush into motion. The two commanders, Domel and Okita, vie for ultimate victory and survival.

Yuki is taken to the Gamilan prison planet of Leptapoda. Kodai is sent to the same planet to scout out supplies for the Yamato.

With a Wave Motion Gun in Gamilan possession, the Yamato’s only option is to take the fight to Gamilas’ capital. Meanwhile, Kodai is given permission to rescue Yuki.
