Afterword
"Thanks for your patience. Volume 8 is finally here. I think at least some of you have already read the webseries version of this content—it’s actually part of the Demon Capital Opens arc. Why did the title of this volume change? Well, there’s a good story behind that… “Don’t worry! I promise I’ll keep it nice and compact this time!” “I’ve heard that one before. I don’t bother worrying much about the length by this point.” That’s how I kicked off this volume, and then when the deadline drew closer…  “Um, we need to talk.” “Yeah, yeah, what is it?” “Well, it’s starting to get a little long, actually…” “It is, huh? I figured as much.”  My editor, Mr. I, was wholly unmoved.  But my turn wasn’t over yet!  “Could we make this a two-volume story arc?” “Huhhh?!” “Because I could write a hundred more pages, and it’ll still end in kind of a half-assed position. How about we shake things up and go with a two-parter?” “No! Why’d it come down to this?!” It was a very heartwarming conversation, one that ended with Mr. I’s eyes rolling all the way back inside his head. ******************** So yeah. I have some regrets. Not even I am entirely sure why it turned out like this, but lately I’ve started to think it’s a little impossible to condense this story. Thus, I’m working hard to finish up the Demon Capital Opens arc in Volume 9. I’m trying to make sure this doesn’t turn into a trilogy, so I hope you’ll come along for the ride. See you in the next volume!"
