So I'm too impatient to wait for the anime, so I started reading Diamond is Unbreakable.
It is really good. At first it just came off as a typical Shonen of Japanese high school students getting into wacky supernatural events, but it feels like using a typical setting and combining it with the best parts of JoJo to create something totally fresh. The chapters at the Italian restaurant and Koichi's stalker were amazing.
Seeing Joseph, the showboating jerkface with a heart of gold from Parts 2 and 3, turn into this doddering old fogey is surprisingly sad.
Promise me it never turns into a Tournament Arc.
