the resolution combined with the dot matrix printing's dithering makes it act weird on smaller screens.

Page 16 seems to be missing.

Also I recommend you save the b&w pages in grayscale PNG, it's much more suitable for this kind of content, and despite being lossless the filesize goes down by 80% (or by 90% to 39 MB when saved in 16 grayscales at no loss of visual quality).

About the torrent of the resize version (uploaded by Momo_Yuki), it's missing page 3, page 22 and like piespy said, page 16 which is not in this gallery but does in the RAW (https://e-hentai.org/s/f0e979d93c/1042775-15).
But the resize version is a bit strange to look at as there are some white mark which is very noticible on grey color (sorry, I don't know the technical word to call them).

I've uploaded a resized 1280x torrent for you guys. I could not notice any quality difference between 2400x and 1280x so I choose 1280x since it's smaller.

Typically galleries with absurd file sizes for only few dozen pages is because the uploader uploaded the file in png format or some lossless quality.

A Shiokonbu Idolm@ster story that's vanilla... a SHIBUYA RIN Idolm@ster story that's vanilla.
It doesn't seem to be here, but I get the feeling that Shiokonbu had this as the prequel to a story where Shibuya Rin gets gangraped by the executives and sponsors of the Cinderella Girls, it's the only thing that makes any sense cause Shiokonbu doesn't do vanilla and Shibuya Rin doesn't get vanilla non-rape love.
