So people tend to say this is really generic. which I agree with, but THATS THE POINT. Okay, you have a teenage boy who gets powers and goes to a school, then becomes a bit too overpowered. Basic shounen formula, right? But for some reason, Jujutsu Kaisen does it really well. It gets more complicated in the Shibuya Arc, some people may like it and some don't(I personally do.)
Some people may disagree with this, but I feel like the characters aren't really worth obsessing over. Which was probably why my JJK phase was so short. Their designs and personality seem pretty natural, which may seem like a good thing, but its kinda basic.
