i've managed to rip some of the more recent galleries from Koushouku using basic screenshotting and dumped it into MEGA.nz.

Note: Quality isn't super high and there is a bit of JPEG compression because it's screenshots. Expect 2400pixel resolution at maximum. Yes the files have (webp) in the filename but it's all JPEGS, misleading I know.
Feel free to redistribute. Link will stop working in 12 hours from now.
