Toru decides to make a pact with Fredrika by becoming a Dragoon Cavalier in order to fight Arthur while Akari, Vivi, Leonardo, Red Chaika and her companions face off against Black Chaika and her minions. Assisted by Chaika and her Gundo sniper rifle to enter the space fortress, Toru battles against Shin before finally defeating him. Red Chaika faces off against Black Chaika before giving her the finishing blow, ending the latter controls of Alina, Irina, and the Chaika warriors.
