Light (Lantern)
The preparation of the bone festival is underway. Canon and Sakura make amends for what happened during the recent alien invasion. It is seen that Koyo, in his assimilated state, is released by Tsubaki after Chizuru had froze him in the capsule. The islanders enjoy the evening at the bone festival. The following day, the pilots realize that Koyo has left the base. They barricade him in a shrine to protect him. Soushi spars with Kazuki, while Kyouhei prepares to snipe Koyo. When Canon arrives, Koyo is reminded of Shoko from her clothing, as he is brought back to normal from his assimilated state.

Fafner
Tatsumiyajima is the central island in the middle of a small cluster of islands, in a sleepy backwater of the Japanese isles. Not much happens there, and the island's young people go to school knowing that their lives are likely to remain peaceful and undisturbed. Or so they have been taught... but the truth is different. The fate of mankind is on the line, and Tatsumiyajima is the last line of defense against a hostile and incomprehensible enemy. At the center of it all, fighting for Humanity's continued existence, is the giant robot Fafner, the dragon that guards this final treasure of mankind.
