@Shareazu Only 4 chapters left in volume 8, one of which is just 6 pages like chapter 71. After that, the wiki only lists 7 other chapters to exist, and I won't be doing those until volume 9 releases (unless the series gets gigacanceled or some unexpected event like that). So I'm getting close to, for the time being, "finishing" Ueno-san.
It's actually sort of rare for Ueno-san to make me laugh out loud - it's generally just wryly amusing. That last page made me laugh out loud though, and still does every time I look at it.
