I think you might've missed some cool input from Gege.
But that would require you to reread the whole JJK or just swim thru chapters and pause at specific points.
Gege not only explain power system in early chapters. He actually adds upon that in post chapter comments where he explains what appears to be hard to undersand in his power scaling.
He is genuinely the GOAT of this generation.
Meanwhile OP, MHA and other shits.
yeah stuff happens because stuff happens, dont expect me to explain.
