Reigen's spin-off, 'Mob Psycho 100: Reigen,' is this wild, hilarious, and surprisingly deep dive into his character that I absolutely adore. The manga peels back layers of his con-man persona, revealing how he stumbles into actual supernatural cases without Mob around. The best part? It forces him to confront his own flaws—his habit of bluffing, his loneliness, and even his buried sense of morality. There’s this one arc where he gets trapped in a haunted office building, and instead of running, he actually tries to help the spirits. It’s chaotic, but you see glimpses of the genuine kindness that makes Mob trust him.
By the end, Reigen doesn’t magically become a psychic or a hero, but he grows in his own way. He starts owning up to his lies (sometimes) and even earns a bit of respect from other espers. The series balances slapstick humor with quiet moments where you realize he’s just a guy trying to do his best, even if his methods are… questionable. It’s a perfect companion to the main story—less about powers and more about the messy humanity of its most entertaining fraud.
