I feel like chapter seventy’s title image ought to be a reference to something, but my usual resources are coming up blank. I’ll come back and edit this if I figure it out later.
Page 4, final panel, Bocchi’s chant here is the Kuji-in… again, as we saw it before back in chapter 34
Page 5, have we ever seen Sasaki in colour before? I could not work out who that was on the front cover until I hit this page…
Page 7, 必勝カツ丼 is, I’m fairly sure, a common good luck charm in the real world too - because カツ sounds like 勝つ.
Page 9, final panel, Bocchi misspeaks クリムト as Kurihama.
Page 10, I mentioned being unsure back in chapter 46 how the internet correlated クリムトの夜 with YOASOBI - presumably this description of their backstory matches the real-world duo, especially that they’re comprised of a composer and a vocalist.
I’m trying to figure out how those back-to-front kana that Ame often starts her lines with are supposed to be pronounced…
