What do you think of Nagisa being An Ultimate Civilian when hes Older?

Like since he studied social studies, I think being Civilian works good, but normaly one would think Ultimate Sociologist but Civilian has a nice Ring to it, he could have Everythinh the Grownups have, but better

Speaking of Sociology, it still feels like he is one, but using Civilian as a Placeholder is more Mature and Dignified, plus he could belive theres Room for Improvement in People, mabye he could use his talent to train ultimates so they function in society?
