Even though Mob Psycho 100 finished in 2022, the anime and manga still stand out as some of the best of their generation. The comedic shonen anime features Mob, a young Esper, as he traverses the ups and downs of middle school while working for Reigen Arataka, a fraudulent exorcism specialist. The two go on many adventures that result in Mob often saving the day with his exceptional strength and power.
Throughout the show, a multitude of characters offer depth and serve a unique purpose to the story. Many of these characters, however, become underrated compared to the main characters. They deserve a shoutout for the role they play.
8 Shiratri Brothers
Telepath Espers
- Debut: Anime Episode 6; Manga Chapter 22
The Shiratri brothers emerge as part of Kenji’s Esper group, with their psychic powers being awakened through lab work. The brothers’ ability allows them to communicate with each other even when they are not in the same location.
At first, Ritsu believes the Shiratri brothers and the other Esper subjects are pathetic due to their weak abilities. It’s only when the Esper group and Ritsu get captured that Daichi and Kaito’s ability comes into play. Muto, a strong Esper that belonged to Claw, supposedly killed Kaito, showing the body to the captured group. Only after Muto disappears does Daichi reveal that Kaito is alive and well, with Muto faking Kaito’s death, revealed by both the brothers’ telepathy powers.

After Claws’ fall, Serizawa joins Reigen and Shigeo at the Spirits and Such Consultation Office.

Although Musashi’s towering and physical appearance may appear off-putting, his actions and leadership make the character stand out. Musashi is the leader of the Body Improvement Club at Shigeo’s middle school, which Shigeo later joins, to the dismay of the Telepathy Club. Although losing Mob as a potential member puts a dent in the Telepathy Club’s plans, Musashi lets them stay in their designated room as the Body Improvement Club only requires the space for equipment.
