https://www.dlsite.com/books/work/=/product_id/BJ395395.html Don't mind the weird filenumbers, I extracted the images that could be extractered, and rendered the novel pages due to them being text, so I organised from two sets of files, it is in order. The few weird number skips are there for a reason as well, but it is complete.
Suggestions: - You could optimize pages with text, even if they has additional colored elements it doesn't mean you have to save 100% color quality there. Converting to 16 colors and then applying PNG crunching app like pinga should do the job. - Since most pages are text, it wouldn't hurt to upload the original PDF for anyone who would like to read it on their screens at any dpi.
