au where teru lives with reigen bc reigen is his uncle who stepped up to take care of him
some fun stuff i've been thinking abt this au for a sec:
part, if not the whole reason, why reigen employs mob is bc he thinks teru could use a friend who also has psychic powers
for the first 4 years teru doesnt like mob and doesnt make any effort to get to know him at all until they have a fight at school
mob is not actually that aware that teru lives with reigen, he only learns about it after he ends up there during the seventh division arc
when teru says "he is just a regular student" abt mob (during the world domination arc) teru really means it bc its ingrained in his brain since they met that they are just some kids in reigen's eyes
the haircut during the seventh division arc happens but only bc teru was pissing off sakurai not bc the wig was ugly (bc he doesnt have a wig lmao)
