The enemy is starting attack villages and another solar eclipse is about to happen. The empire has formed an army with Louise and Guiche to avert the attack. Saito finds out and uses the plane to come to their aid, but he has to give up his chance to return home.

After the battle, the solar eclipse is over and the plane is nearly destroyed. Saito ends up staying.
