Reigen's got an invitation for a big job that could relieve his money woes forever. He bids Mob and Dimple tag along.
The gazillionaire CEO Masashi Asagiri has called upon every psychic in the area to save his daughter Minori, whom he believes is possessed by an evil spirit. No one else in attendance—including Mob—senses any spirit energy from the restrained 14-year-old girl, and the crowd's suspicions come to rest on her father. Reigen, however, immediately notices something fishy upon his turn to chat with her.
When he describes the inconsistencies in her speech and chastises the other psychics for not trusting their client, the spirit reveals itself, immediately attacking everyone present. Dimple is terrified. He'd nearly been exorcised and absorbed by this spirit when it was human: the famous former psychic Keiji Mogami, his wish to become the most powerful evil spirit in existence fulfilled. Mob has never heard of him, but his work was an inspiration to Reigen when he started his business. Dimple explains.
Decades ago, Mogami was a kind, helpful and wildly popular spirit medium who regularly appeared on TV. When his mother became sick with a mysterious illness, he informed his audience. None of his many, many fans offered to help. Mogami then became a spiritual hitman of sorts to raise money for her treatment. But she died anyway, cursing him as her spirit fled her body. Mogami spent the rest of his days literally gorging himself on evil spirit energy, then took his own life. The green ghost never thought he'd see Mogami again.
Mob resolves to save Minori himself, and elects to use a technique he'd learned from a previous client's stalker—an out-of-body experience—to go within the girl and chase Mogami out. He asks Dimple to possess his body while he's gone... wait. The former cult leader gets his wish and doesn't have to seize Mob's amazing power by force? He is delighted at the opportunity, and distracts the vengeful psychic long enough for Mob's soul to dive into her body.
The child, now naked and vulnerable, goes on the offense against Mogami in the mental world he's built inside Minori. Despite the young Kageyama's immense power advantage, Mogami crushes him underfoot. The man then strips him of his psychic gifts... and his memories...
Tropes appearing in this episode include:
- All for Nothing: Mogami's murders for hire to raise money for his mother's medical treatment.
- Assassin Outclassin': Mogami is shown walking away from a pile of bodies at one point, presumably of those who sought to kill him for lethal curses he'd laid.
- Astral Projection: How Mob enters Minori.
- Energy Absorption: How Mogami gained all that strength before his death, and how he brings Mob's immense power to heel. Mob puts this skill to good use later in the series.
- Impaled with Extreme Prejudice: Mogami in Minori's body—to her father.
- Instant Expert: Mob has never tried astral projection before, and never saw how the stalker from the previous episode accomplished this. He figures it out himself.
- Lotus-Eater Machine: Mogami creates one inside of Minori's body when Mob invades with the idea of turning him into a sympathizer of his twisted ideals.
- Out-of-Clothes Experience: To emphasize Mob's innocence in comparison to Mogami, the supernatural origins of Mogami's mental plane, and possibly also to highlight Mob's vulnerability, belying the assertive tone of his voice. Given that the two psychics' appearance in Mogami's metaphysical space mirrors how they see themselves...
- Poor Communication Kills: Mogami. It apparently never occurred to him to simply ask his huge fanbase outright for their financial support. Bitterness over his unspoken needs and knowledge that his turn to crime to save his mother was indirectly responsible for her death...breaks him. He later commits suicide.
- Villain Takes an Interest: The former TV psychic claims a spiritual kinship with Mob and aims to break him of what he sees as a naive worldview.
