Lore & Background

Claw Service operates on the belief that psychic abilities grant superiority over ordinary humans, justifying their aggressive recruitment tactics. They view Mob as an anomaly whose energy could elevate them to godhood if controlled. Their structure is hierarchical, with Teru Hashima leading from the top while enforcers handle field operations against perceived threats. While Reigen Arataka lacks actual abilities, his cunning and charisma allow him to navigate conflicts that would crush a normal person. Dimple, the parasitic spirit residing within Mob's mind, constantly urges Shigeo to unleash his full potential, creating internal conflict between self-control and emotional release during these confrontations.

In Their Own Story

Rain slicks the pavement as Reigen adjusts his glasses, sweat beading on his forehead despite the cool air. Behind him, Shigeo stands silent, eyes closed, sensing the heavy pressure of psychic energy gathering in the alleyway. The leader of Claw Service steps from the shadows, smirking at the fraud's trembling hands.

Reader's Guide

The narrative begins with Shigeo Kageyama navigating middle school life while suppressing immense psychic energy under Reigen Arataka's employment. Tension rises when Claw Service, a rogue psychic organization, targets Mob to harvest his unique power for their own agenda. Early encounters reveal the group's ruthless tactics as they abduct friends and threaten civilians to draw Mob out. Reigen attempts to handle the threat alone using deception and luck, but the situation escalates beyond bluffing. A major turning point occurs when Claw Service leader Teru Hashima confronts them directly, forcing a confrontation where Reigen's lack of real power becomes glaringly obvious. Despite this, Reigen steps forward to protect his apprentice from harm. The climax arrives as Mob finally breaks through his emotional suppression, unleashing the psychic energy he has held back for so long. This release destroys Claw Service's immediate threat and solidifies the bond between master and student. The arc concludes with Mob accepting that emotions drive power, while Reigen continues his fraudulent business with a newfound sense of genuine responsibility toward Shigeo.
