Makina Hoshimura, a deceased teenager reanimated as a Shikabane-Hime (Corpse Princess) under control of a secretive sect of Buddhist Monks, is introduced as she continues her mission to eliminate other undead Shikabane on Earth using her fists, feet or dual-wielded MAC-10 submachine pistols. Her target is Hagino, a charismatic psychopath with a penchant for serial-killing women, who rose from the dead as a Shikabane. Local high school student and orphan Ouri Kagami's world is shaken when he encounters Makina after she is knocked out during an early encounter with the monstrous Hagino. Unbeknownst to Ouri, his older brother-figure, Keisei Tagami, is somehow involved with Makina as well.
