Teruki used to be very temperamental and self-centered, but after an awakening encounter with Mob, he’s learned how to see other people, and especially admires Mob for his abilities and restraint.

Ritsu is Mob’s little brother. He’s only recently awakened his Esper abilities, not being born with awakened abilities like Mob or Teru. He cares deeply about his older brother, especially after the events in the Claw facility. He aspires to be strong like his brother, and sees his popularity as pointless when faced with how extraordinary his brother is.

Mob’s mentor, and a shady conman. He runs a fraudulent exorcism business, with Mob as his only worker. He pretends to be a powerful psychic, but leaves Mob to handle real evil spirits since he’s completely ordinary in reality. He teaches Mob how to balance his life with his abilities, giving him restraint and rules that help him control his powers.
