Ep. 1: Inaho awakens Aldnoah powers after Asseylum's blood grants him control over the Deucalion.
Nineteen months after the Saazbaum Landing Castle incident, the Vers Empire, led by Slaine and Princess Asseylum, expands its conquest across North and South America. A UFE raiding party is ambushed by Slaine in the Tharsis. On Earth, the Deucalion crew faces the Frozen Elysium, a Martian Kataphract that freezes targets instantly. Inaho arrives in the KG-6 Sleipnir, using airburst grenades to breach the freezing field and defeat the enemy. Flashbacks reveal that after being shot, Inaho ingested Asseylum's blood, granting him Aldnoah Drive activation powers. This ability allowed him to reactivate the Deucalion despite its lack of power. With repairs finished, the Deucalion launches into space. Meanwhile, the Princess delivering war speeches to the Vers Empire is revealed to be Lemrina, disguised as Asseylum under Saazbaum's orders. Slaine visits the real Asseylum, who remains alive in a medical tank.
