Naoto Saki is a typical young boy whose favorite thing to do is sleep and dream about a fantasy world called Orgos, where he is just an observer. But, one day, Naoto is magically summoned into Orgos as slave to a sorceress named Lusia. Suddenly, Orgos is no longer a dream--Naoto can feel pain and possibly even die there. All he wants is to go home, but Lusia has other plans for him.
