I was recently introduced to Jason Shiga's Demon, a webcomic that he has since released in paper form, apparently in four volumes. My local library only has the first three (Amazon lists the fourth volume as to be released on November 17th, 2017). I found PDFs on his site for 20 chapters, but the 20th ends fairly abruptly with
Jimmy and Hunter having a final showdown at the top of a Japanese castle, Hunter holding a katana to the neck of Sweet Pea.
Are there more than 20 chapters? Is there an actual end to the story or does it end with the standoff?
