Having stolen a robot, complete with a stowaway, Cacao and Parfait now must figure out what's going on. But now the Fourth Warrior knows who they are, and he demands they serve him as Holy Virgins should.

Cacao steals away in the night to talk to the Fourth Warrior face to face. Aboard his ship, she learns his goal, and what kind of man he is. Meanwhile, Parfait attempts a rescue mission using her new robot.

Parfait continues to pursue after Cacao and the Fourth Warrior. Meanwhile, as Cacao resists the Warrior's advances, cracks begin to form in Electone's cold expression.

Cacao, Parfait, and Lemon confront Don Vodka, the leader of the Giga Genos. There, he explains the truth behind the Fourth Warrior, behind the Genos themselves, and how Parfait and Cacao fit into everything.

The Mystic Knight has awakened, but that isn't necessarily a good thing! Parfait and Cacao struggle against its absurd power, but in the end, they'll find the answer was closer than they thought.
