Ep. 10: Zeravire threatens city with theta rays while Eiji rescues Cecile from its grasp.
The Gran Phantom System underperforms compared to the piloted Gravion during a city shopping trip. A Zeravire appears, destroying buildings to form a cocoon and emitting theta rays that will kill everyone within one hundred kilometers in thirty minutes. Cecile falls underground, prompting Eiji to jump down to save her. Mizuki arrives with the Gravion while Eina and Luna fly overhead. The team combines the Gravion and uses the Gran Phantom System to pilot the G-Attacker. Despite shooting the Zeravire's tentacles, the machine cannot get close. Eiji runs toward the creature to reach Cecile. Toga orders the Gravion and Luna in the G-Driller to attack, but Eiji pleads for them to wait. Just as Eiji reaches Cecile, Toga fires the Graviton Arc, blowing Eiji away. The Gravion destroys the Zeravire with the Gravity Crescent seconds before radiation release. Eiji punches Toga for sacrificing Cecile and announces he is quitting.
