Bought this myself on dlsite, support the author if you liked the work and can spend 5 bucks. The provided reader that came with the archive was some proprietary DLsite stuff, files weren't even in pdf. Had to extract using a special tool the name of which has escaped my mind. It's probably "DLsite ripper".
After that i noticed images had compression artifacts in them so i went on to denoising them using waifu2x. The settings used were: Real-CUGAN-NCNN-Vulkan for engine settings, model cunet and denoising at level 3. This converts black and white images to rgb so i converted them back to grayscale. If you want to have a look at the original archive then look in the torrents section.
