Akemi Itō is a human character from Myōjin University, recognized as a campus idol. Her background includes a romantic relationship with Tatsuo Nagumo, the human destined to become the vessel for the Chōjin (Overfiend), positioning her as the prophesied mother of this messiah figure meant to unite multiple worlds. Her characterization varies between adaptations. The anime portrays her with innocence, naivety, and relative sexual inexperience, contrasting with other characters. Conversely, the manga depicts her as more sexually adventurous and preoccupied with sexual experiences, also establishing a rivalry with Megumi Amano due to Nagumo's romantic choice favoring Akemi. Akemi's narrative function centers on her relationship with Nagumo and her role in the Chōjin prophecy. She becomes pregnant with Nagumo's child, identified as the future messianic entity destined to bring about a new world order after cataclysmic destruction. This pregnancy is a critical plot element across the saga. Surviving Nagumo's transformation into the Destroyer Demon and the ensuing apocalyptic devastation, Akemi carries the unborn Chōjin. Her later portrayal reflects the physical and emotional toll of these events. Her ultimate fate involves giving birth to the Chōjin under traumatic circumstances, depicted as a grotesque merging of birthing and self-pleasuring imagery, fulfilling the central prophecy.
