Hiro, Hime, Flandre, Riza, and Reiri are trying to find the royal sibling responsible for sending Dracul and the three werewolves, ending up at a town. In an abandoned warehouse, Riza and Reiri are distracted when a female warrior named Micasa fights them both. The town is then populated with zombies, and they have no idea who caused this. To make matters worse, Flandre powers down while the group tries to hold back the zombies till morning. Micasa, who briefly reports to her master Severin, another one of Hime's older brothers, returns to fight Riza. After Flandre is recharged, Sherwood, Francisca, and Ryu-ryu arrive to help the group take out the zombies, while Riza manages to defeat Micasa.

Flandre acts strangely and goes on a rampage, repeatedly attacking Hiro. Hime catches attention of this and contacts Sherwood about it. While the two analyze Flandre's data in the laboratory, Hiro and Riza try to follow Flandre from the pass to the shopping district. Although it is a wild goose chase for them, she is thought to have saved many people in the city. Finally catching up to them at a power plant, Hime tells Hiro and Riza that Flandre will self-destruct soon, and Sherwood sends Francisca to battle Flandre, but to no use. Flandre heads into the ocean, but as it seems that she has self-destructed, Emile briefly appears with his android Flanders and tightens the loose screw on Flandre's head, being the reason for her misbehavior.
