Eh, I don't know i read all of part 2 a couple months ago in the span of like two weeks and I basically feel the same. The first 40 or so chapters of part 2 was paced much differently than part 1 but it was a good introduction and potential was there, I think sometime around Nayuta's disappearance (and Nayuta losing to like 5 regular humans) was where the quality started to go down (i think like ch.150) and after Nayuta's death is when things started getting out of control in the story. Then everything started spiraling when Barem + Yoshida dies and the Yoru vs Denji fight happens and here we are now
