Keiji Mogami

Keiji Mogami was once a celebrated esper standing at the pinnacle of his field, but after seeing through the inherent selfishness and ugliness lurking within human nature, he fell into profound despair and took his own life. In death, he was reborn as an extraordinarily powerful evil spirit. During the Asagiri Minori arc, he traps Shigeo Kageyama within a torturous mental realm, subjecting him to cruel ordeals designed to expose the darkness of humanity. As a pivotal antagonist, Mogami serves as the catalyst for Shigeo's spiritual awakening and the ultimate challenge to his core values.
