>>279630637 (OP)I don't think normies know about Solo Leveling.
I think it's mostly shilled by bots but out of the fans who are actually humans they are mostly shonentards.
Now shonentards aren't the same thing as normal fags, they might be more common than right and proper otaku but they are still a fringe.
So I wouldn't consider something like JJK that was popular with every shonentard 'normie', that being said normies might have heard about whatever the big shonen more than other anime because they are somewhat likely to know a shonentard.
The most consistent thing known by normies is Studio Ghibli and not much else but Attack on Titan did break into the normie sphere briefly. Edgerunners and Frieren have skirted the edge of normiedom but not really penetrated inward.
