In the waking world, Rem appears to be an ordinary woman, but within the realm of dreams, she transforms into a dream warrior dedicated to protecting humanity from the evil forces lurking there. When dream demons manage to cross over into reality, she combats them with the aid of her pets, which can assume the forms of a tiger and a wolf.
This series originally debuted as a single-episode OVA containing explicit sexual material. Following its release, the production approach shifted; the first episode was reissued alongside a second episode, with all sexual content removed and replaced by new scenes. The subsequent second and third episodes followed this revised direction and likewise contain no sexual content.
