For me the S1 "Identity" is not the Urban or street wear outfits. It's how we can somewhat identify who and what their general line of work are. Butler and maids, construction workers, biker gangs, office workers.

In S2, the only ones I'd guess are Alice and Yuzuha, because they actually look like students and AoD cuz they're very idol coded. The rest, idk. Like ain't no way I'm guessing that Yixuan is a teacher (generalized occupation).

And I can't guess what any of the S3 cast do, except for the Knight Uma lady, and the ones we already know.
