Etna by holding her memory. He had instructed her to kill the prince, but she had put him to sleep for two years by poisoning him instead. Etna eventually betrays Maderas, and along with Laharl, Flonne, and Mid-Boss, defeats him. Waking up later at night, Flonne discovers that several Prinnies are chanting and leaving the castle. Laharl, worried that his reputation will be tarnished if it is discovered that he let his vassals escape, chases after them the next morning. Eventually, he runs into Death, and the player learns that Big Sis Prinny is actually Laharl's mother; she became a Prinny because she gave her life to save him.

Vulcanus reveals to Laharl and his party that he intends to conquer all three worlds and rule over them as a god.
