So, when I said "I'm hoping to release a chapter every three days," that was code for I'll probably be releasing a chapter every day. So here is Chapter 4, and the plot is picking up pretty quickly! (Faster than part 3 IMO.)
Since I get to bitch here, Photoshop merged all of my text layers to the original, so going back for spellchecking was a bitch.
I don't have a translation for the brief biography of Josuke at the beginning of this chapter, I'll work on getting all of those by the time I release a batch for volume 29.
