the main road with hot water river in middle and bridges every 50m, the wood stairs, the waterways and the yumomi reference... bruh, that's totally kusatsu onsen!
So glad we got another chapter. Seriously this is probably one of if not the greatest Manga of all time. It’s got a little of everything plus interesting characters, an amazing world, and beautiful art. I truly hope this continues for many hundred more chapters and it damned well deserves an Anime.
