After his battle with the Empire, Alnoa sets his mind to learning more about the mysterious Demon King. He resorts to summoning the succubus Lilicia for information, and she has a surprising secret to share with him. According to her, Al needs to perform the so-called "Heavenly Surge" with all seven divas in order to renew the seal keeping the Demon King at bay. If he fails, there will be cataclysmic consequences. But unfortunately, Feena—the only Diva he can make it to in time—is dead set on avoiding him!
