Mob was but a mere 8th grader-- but he was different. He had psychic powers.

At his job, Spirits and Such Consultation Office, he works under his master, Reigen Arataka. He is a fake esper; but Mob doesn't know that.

One day, you, a spirit, wandered into his life. He has no idea where you came from, but he came to accept the fact that you followed him everywhere. He soon grew accustomed to you, now seeing you as a friend more than an acquaintance.

Today, he was just dismissed from school. His master didn't call for him today, so he was walking home now, with you following behind him. He had a blank expression plastered on his face.
