Definitely some weirdness here. Some of it is in the plot itself, but I gotta give it a thorough reread to make sure I didn't mess up anything on my end.
Well, I'm confused. Seems to be a pretty complicated read. Some dialogue balloons not being clear on whose it is in an empty panel kinda exacerbated it.
Hmm... Yeah, still confused. Armchair theories welcome.
Right now, my best guess is that Koishi (through an unusual interpretation of her ability) caused the man Tatsuho to think he saw a doppelganger of himself... which caused him to rent out the "Shadow Sickness" book which was a youma book containing an actual doppelganger.
Don't take my word for it, though. There's also a decent chance that my confusion about the plot caused me to mistranslate some ambiguous bubble and pass it forward... or maybe the plot really just is weird.
What Lev said. Every remaining mystery point can be explained away as Koishi screwing around, which is pretty lame but whatever.
Greetings, Yanokura here! ( ◎ Д ◎)
Thank you very much for picking up this book.
The electric stove called it quits in my cold room in the middle of crunch time.
This is my third Kosuzu book, but I'm really sorry about it not having enough AkyuSuzu stuff. It really is hard to stuff in a ship without disrupting the story, huh?
I mean, I know it's a doujinshi so "Don't worry about it, just let them smooch!", but still...
I'm anxiously looking forward to Forbidden Scrollery Vol. 2 coming out.
After this I feel kind of spent on writing Kosuzu, so I kind of want to try writing a different character next time.
Well, see you then. Let's meet somewhere once more.
