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!
