Akemi Itō is a human student at Myōjin University. Anime adaptations portray her as young, innocent, and naive. She forms a romantic relationship with Tatsuo Nagumo, the human destined to become the vessel for the Chōjin (Overfiend), and is fated to bear his child, a figure destined to shape the new world. This relationship positions her centrally within the apocalyptic events triggered by the prophecy of the three worlds' merging. Her manga characterization differs significantly, depicting her as more sexually adventurous and occasionally manipulative. She engages in a rivalry with Megumi Amano for Nagumo's affections, leading to jealousy-driven conflicts. The manga emphasizes her overt sexuality and interactions with supernatural forces over innocence. Across both media, Akemi faces victimization by antagonistic entities. In the anime, she is sexually assaulted by the demonic teacher Togami (disguised as human), an attack interrupted by Amano Jyaku who destroys Togami. Later, in *Legend of the Demon Womb*, she is targeted indirectly through Takeaki Kiryū, Nagumo's cousin. Under the control of the diabolist Münchhausen II, Takeaki commits violent and sexual assaults, including against those close to him. Akemi survives these ordeals but endures significant trauma. As Nagumo transforms into the Chōjin, Akemi becomes pregnant with his child, destined to be the messianic figure who rebuilds the world after its destruction, positioning her as the symbolic mother of the new era. Her agency remains limited compared to the supernatural beings manipulating events. In *Legend of the Demon Womb*, Münchhausen II's machinations escalate the conflict, aiming to resurrect the Kyō-Ō (Evil King) through Takeaki. Akemi witnesses the resulting chaos and battles involving Amano Jyaku and Megumi, but her narrative primarily revolves around her connection to Nagumo and her survival amid escalating violence. Her ultimate fate ties directly to the prophecy's fulfillment, where her child represents the future hope for the merged worlds.
