After a furious leveling session, Illusia finally evolved into his next form: the double-headed dragon of eternity, Ouroboros. Tiny problem, though--that second head has a mind of its own! Illusia soon heads to Harunae with Ballrabbit and Adoff in tow to do whatever he can to save Nina from her impending execution. And after that, it's time for a rematch with the other Illusia. But will the second head cooperate with Illusia's plans?
