Ep. 10: Arthur advances to his space fortress while Toru and Chaika's forces confront his allies and the Emperor himself.

Arthur travels to a space fortress with Shin after destroying Six Nations flying fortresses. Toru becomes a Dragoon Cavalier to fight Arthur, while Akari, Vivi, Leonardo, Red Chaika, and others battle Black Chaika. Toru enters the fortress with Chaika’s Gundo sniper rifle, defeats Shin, and faces Arthur. The Emperor offers Toru a place in his army, claiming war is humanity's desire, but Toru refuses. Arthur and Fredrika are defeated, and Chaika shields them. Arthur attempts to kill Chaika with Niva, but the weapon refuses and joins Chaika. Using her memories as fuel for Niva’s Cannon Gundo form, Chaika kills Arthur, ending his plans. Alberic reports to the Council of Six Nations that Arthur’s schemes failed and all Chaikas died. Toru, Akari, Chaika, Fredrika, and Red Chaika live together, with Toru assisting the recovering Chaika.
