Bride of Deimos revolves around high school girl Minako Ifu, who has become the focus of the attentions of the demon Deimos. Minako appears to be the physical reincarnation of Deimos' lover and younger twin sister, Venus, the former goddess of love. In order to rescue Venus from the fatal punishment she received as a result of their relationship, he has to bring Minako to the underworld so Venus can possess her body. Over the course of the manga, the reader sees the various ways that Deimos attempts to accomplish this, interspersed with random chapters of Deimos involved in bringing suffering and death to whichever humans he happens to encounter.
