Ep. 8: Sky Clan attacks Isla while an unknown seagull-flagged plane from the Holy Levamme Empire intervenes.
Sky Clan bombers assault the island, prompting Van Whyl class students and Cadoques High regulars to engage. Outmatched, Fausto orders a defensive formation while Benjamin, Sharon, Nanako, and Noriaki repel paratroopers on the ground. Ignacio stops Claire from shooting, demonstrating superior skill. Airborne students suffer heavy losses; Fausto and Wolfgang die, and Marco and Ariel are wounded during a retreat. Kal-El fights to return to Isla, pursued by enemies, until an unidentified plane with a seagull flag destroys the attackers. This ally allows Kal-El to reach safety. The next day, Kal-El visits the hospitalized Ariel. The Council translates a message from the unknown plane, revealing it originates from the Holy Levamme Empire, a nation sharing religious beliefs and interest in the Holy Spring, which seeks to meet the people of Isla.
