I just picked up 4 volumes of 空の青さを知る人よ for 396 yen
Never heard of the series, but quickly checked the sample and it has furigana and looks relatively beginner friendly(?) But more importantly it was really cheap!
Please share if there’s any series that are really worth picking up
Along with あの日見た花の名前を僕達はまだ知らない and 心が叫びたがってるんだ, it’s considered part of the Chichibu “trilogy” - three anime films written by Okada Mari that, aside from all of them being set in Chichibu (Okada’s birthplace), are otherwise completely unconnected. It is, I confess, my least favourite of the three.
The manga is based on the movie.
