Both has pretty typical Evangelion tier pacing but come on.
Persona 4 is:
Two people are murdered in quick succession
Then all these other kidnappings happen
For some reason they can't catch the guy until he literally decides to go in with his victim for no reason
The twist is literally that there were two "killers" and one was just a mentally retarded stooge.
Real killer gets outed because Naoto does the oldest "Detective pretends to know who the killer is when they really want the murderer to blurt out their motives" routine in the book
Blah blah blah Undead bitch did it for shits and giggles
