Four hundred years ago, the evil spirit Nabeura Sakon was sealed away, but now he plots to burn Tokyo to the ground in order to resurrect his master, Sagisaka Hoki no Kami. Standing against him is Kita no Komi, the descendant of the original seal master and the magical warrior Sailor Heat. However, Sakon possesses her grandfather, paralyzes Komi with a poisoned arrow, and imprisons her as his captive within a sub-space of his own creation. Once a famed warrior known in the history of Koshigawa Castle—and notorious for his lust for women—Sakon now indulges himself in a female body for the first time in 400 years, violating Sailor Heat's body without mercy. He steals her first kiss, torments her nipples, and ultimately takes her virginity, something no one else was ever permitted to have. A thrilling and erotic tale depicting the unholy desires of a demonic spirit.
