Poe and Harry join the Soleil while Sochie and Miashei assist Corin with his Kapool. The Almaiya locates the Turn A Gundam, prompting the Willghem to descend as Michael rejects Guin's orders. Loran battles Gym, who intends to use the Turn X to destroy civilization via a Moonlight Butterfly attack. Corin defeats Merrybell but dies from Gym's assault, leading Loran to activate his own Moonlight Butterfly. The abandoned Guin rescues Merrybell and reunites with Michael and Yanny. Sochie aids Harry and Poe in defending the Soleil, which activates its barrier. Loran damages the Turn X, causing Gym to eject the cockpit. The two duel with swords until Gym is sealed by light from both Gundams, allowing Loran to escape thanks to Sochie. With Gym trapped, the war ends. An epilogue reveals Bruno and Jacop start a puppet show, Lily, Horace, and Milita repair the Willghem, Kihel becomes Moonrace Queen with Harry, Fran and Joseph have a baby, Sid takes an apprentice, Keith opens a bakery, and Guin sails with Merrybell. Loran kisses Sochie goodbye as she cries alone, while he and Dianna settle down as husband and wife.
