Following the Third World War, humankind left the toxic surface of the Earth and built an underground city to survive. A serious social problem has emerged in this new society: hyperorexia, or severe overeating, a side effect of the “Pure Trance” life-sustaining pill. The story begins in a hospital which has been ruined by a tyrannical director, Keiko Yamazaki. The nurses who toil under Keiko’s whip are regular girls, just like your friends and co-workers. Yet this is no soap opera! It is a dreamy science fiction fantasy ― a twisted story of catfights, alien safari adventures, evil experimentation, and a girl in love with a pop idol singer.
