Ripped from you-know-where and converted using you-know-what.

The epub should work with most readers that support it, including media server programs like Komga and Kavita.
You can open the EPUB file using 7-Zip or WinRAR. If an image file name contains “kcc-”, it is already in chronological order.
If the image file name contains “image_rsrc” and you want to convert it to JPG, use a tool like Calibre to convert the EPUB to PDF, then to ZIP. See guide below.
(Converting from EPUB directly to ZIP may result in pages being out of order.)
