While traveling through the scorching Harunae Desert, Illusia comes face-to-face with something unbelievable--a human Hero who shares his name! But aside from that, they're nothing alike. Powerful, merciless, and impossibly strong, the Hero easily overpowers him and snatches away Nina, leaving a chilling ultimatum: save her in four days...or else. With no other choice, Illusia throws himself into a brutal race against time, pushing his limits in a desperate bid to level up before the battle to take back Nina. Can he get strong enough before the deadline, or will the other Illusia crush him completely?
