Reigen Arataka is a major character in Mob Psycho 100 by ONE. He runs a spiritual consultation business called Spirits and Such Consultation Office despite having no psychic abilities whatsoever. He employs Mob (Shigeo Kageyama), a genuine psychic, as his assistant. Despite being a con artist by profession, Reigen serves as Mob's primary mentor and moral guide, teaching him that psychic powers do not define his worth as a person. He is consistently ranked as one of the most popular characters in the series.

Does Reigen Have Any Powers?

No. Reigen has no psychic, spiritual, or supernatural abilities. His exorcism techniques include rubbing salt on clients, giving massages, and performing rituals he invented. When confronted by actual spirits, he relies on confidence, social manipulation, and occasionally Mob's intervention. In one notable scene, Mob's power temporarily transfers to Reigen, giving him genuine abilities — but this is an anomaly, not an inherent capability. His lack of powers is central to his character and his role as a mentor.

Why Is Reigen Considered a Good Mentor?

Reigen is considered an excellent mentor because his core message to Mob — that psychic powers do not make you special or superior — is exactly what Mob needs to hear. In a world that values psychic ability above all else, Reigen's insistence that kindness, effort, and personal growth matter more than power provides Mob with a healthy value system. His mentorship is paradoxical: he is a fraud in his profession but genuine in his care for Mob's wellbeing. He never exploits Mob's powers for personal gain despite having every opportunity to do so.

What Is Reigen's Signature Move?

Reigen's signature techniques include Self-Defense Rush (a series of ordinary physical strikes he presents as psychic attacks), Hypnosis Punch (a regular punch), Salt Splash (throwing table salt), and Aura Photography (a normal photograph with a color filter). None of these techniques have any supernatural effect. They work on human clients because of Reigen's confidence and the clients' belief in his authority. They do not work on actual spirits.

Is Reigen a Good Person?

This is debated within the show and by fans. Reigen charges clients for services he cannot genuinely provide, which is fraud. However, many of his clients' problems are psychological rather than supernatural, and his confident reassurance actually helps them. He treats Mob with genuine care, gives him consistently good life advice, and never manipulates him for personal benefit. The series presents him as morally complex rather than simply good or bad — a flawed person who is nonetheless the right mentor for Mob.
