Chapter eighteen forms the remainder of episode ten, plus about the first third of episode eleven. Chapter nineteen is approximately the next, uh… five-twelfths… of episode eleven. From around the seven-and-a-half minute mark to just before the nineteen-minute mark (though there’s a bit of extra content added to pad things out).
Be aware that chapter twenty’s title image is a wide establishing shot rather than the usual album cover reference, so make sure you don’t read too far.
Meanwhile, chapter eighteen’s title image is from “Kongaragatta!” by NECRY TALKIE.
Chapter nineteen’s is from “DOMINATION” by BAND-MAID.
Kessoku Band start chapter eighteen at a famires in Shimokita - the name カスト is a reference to the ガスト chain (and boy did I have to zoom in to read that), but I can’t quite work out exactly where it is. In the anime, though, it’s a Denathan’s (reference to Jonathan’s), and it’s located right here. In the real world, it’s a Burger King, and so far as I can tell, it was never a Jonathan’s (it appears to be some kind of non-chain fish place from 2016 to 2019, and a KFC before that).
Page 44, the typical three Bs of bad boyfriends are reportedly bartenders, band members and beauticians.
Moving ahead to chapter nineteen, the post-apocalyptic thugs on page 52 are presumably a reference to something (Jojo? Fist of the North Star? Just the idea of the genre in general?) but I don’t know the reference well enough to nail it down.
Page 53, Bocchi in black tape is a reference to the music video of “HOT LIMIT” by T.M. Revolution, but I can’t find any site with the actual music video posted besides Apple Music, and you gotta pay for it. The words above Bocchi’s head in that panel are (mostly) lyrics from the song.
I probably don’t need to point out that most of the rest of the chapter is a solid barrage of maid cafe stereotypes.
