Mob Psycho 100 is a Japanese manga series by ONE, revolving around a middle school esper named Shigeo Kageyama, known as “Mob.”
He works as an exorcist’s assistant but secretly aspires to live a normal life without relying on his psychic powers.
Launched online in April 2012 and serialized via the MangaONE app, it achieved wide acclaim, inspiring anime, live-action, and stage adaptations.
Its rich blend of action, comedy, and coming-of-age drama, paired with uniquely expressive art and vibrant characters, quickly captured the hearts of fans worldwide.
Mob Psycho 100 was conceived by ONE, the creator famous for One-Punch Man.
ONE launched the story on Ura Sunday, aiming to explore human emotions through a protagonist with overwhelming psychic abilities.
The creator wanted to challenge the genre with a hero who avoids violence, instead focusing on emotional growth.
The manga received strong reader support, leading to adaptations across several forms of media.
Set in the fictional city of Seasoning City, the world blends normal urban life with hidden supernatural phenomena.
Espers, individuals born with psychic powers, coexist among ordinary people, sometimes living discreetly and sometimes forming secret organizations.
Organizations like "Claw" seek to change the world with their psychic power, while others, like Arataka Reigen's Spirits and Such Consultation Office, approach the supernatural more comically or for personal gain.
The world features schools, cults, and businesses, all with their own relationship to the psychic underworld.
Ordinary life and supernatural elements constantly intersect, giving rise to chaotic, hilarious, and often touching scenarios.
Shigeo Kageyama, nicknamed Mob due to his unassuming presence, is a powerful but humble esper in his second year of middle school.
Haunted by a childhood accident where his powers hurt his younger brother, he vows to never use them against people.
Instead, he works for Arataka Reigen, a self-proclaimed psychic (and hilarious con-artist), performing odd jobs for a laughably low wage.
Despite his overwhelming abilities, Mob struggles with social skills, academic performance, and self-esteem, wishing to win the heart of his childhood crush, Tsubomi Takane.
This journey leads him to join the Body Improvement Club, forsaking the lazy Brain Electromagnetic Waves Club, aiming for a “normal” life.
Mob’s adventures escalate from high school drama to battles with psychics and evil spirits.
He faces corrupt cults, menacing gangs led by rival psychic Teruki Hanazawa, the secret organization Claw bent on world domination, and even gods crafted from public delusion like the giant Psycho-Helmet made from a psychic broccoli tree!
Mob’s circle expands as he confronts tough “delinquent” students, exorcises haunted spots, rescues his brother Ritsu (who gains his own powers after a crisis), and navigates betrayals—including those by Reigen.
As Mob’s emotional meter rises—literally measured as a percentage count—his repressed feelings explode, unleashing even more devastating psychic energy.
Key story arcs include cult confrontations, gang wars, family struggles, psychic tournaments, master-apprentice breakdowns, literal city-wide destruction, and finally, a stormy battle between Mob and his dangerous alter ego “???%” when he’s severely injured.
Throughout, Mob's real conflict isn’t just external foes—but learning to accept himself and live authentically, psychic powers and all.
- Esper: Individuals born with supernatural psychic powers. Abilities vary, from telekinesis to pyrokinesis, sometimes unique or latent.
- 100% / ???%: Mob’s emotional threshold. When the gauge fills, his psychic powers explode according to what emotion filled it (anger, sadness, etc.). “???%” is a berserk state beyond conscious control.
- Spirits and Such Consultation Office: Arataka Reigen's quirky psychic business, serving as Mob’s workplace and comedic home base.
- Claw: Clandestine esper organization with ambitions for world supremacy, divided into multiple branches, each ruled by “Scars” (psychics bearing defeat marks from the boss).
- Body Improvement Club: A positive, musclebound school club intent on personal growth through physical exercise and boundless encouragement.
- Psycho-Helmet Religion: A cult born from urban myth, mistaking Mob’s psychic feats for miracles and worshiping him as a god.
- Psychic Broccoli/Divine Tree: Gigantic psychic-irradiated broccoli sprouting after Mob’s clash with Claw’s leader, becoming the center of a city-wide new religion.
