Part 4 mainly focused at Morioh and finding the arrows & bows + serial killer. However, I feel like other characters are interesting that I sometimes forgot that Josuke is the main mc (Rohan, Koichi, etc). I like Josuke's personality tho but as always I wondered what are the others doing when one of them got troubled. It took times for them to come & it always in the end for rescue etc.
Characters: 8/10

Story: 8/10
I didnt get the whole plot at first, thought they are just finding the stand user who got affected by the arrows but they actually deals with serial killer.
Animation: 8/10
The sudden change in art style but it suits the whole vibes.
