Need help breaking honto.jp's DRM (sh.itjust.works)

I purchased an ebook (two of them, actually) from some Japanese site called honto, but of course, stupid old me didn't realise that Digital Restrictions Management was going to make my life a living hell. Has anyone had any luck with cracking them, or did I just spend 730 Yen on a nothingburger?

Apparently, there are some local files on my phone from "doenloading" the ebook, but they won't load. In the browser I had a little more luck, but the images are scrambled when I attempt to "inspect element".

What do I do? I really want to get this to work...

did you ever figure this out? i'm kinda in a similar situation, though i ended up just using a downloader for the clip studio online reader they provide

I found an excruciatingly manual method of extracting comics which I purchased, but it works well

To make it a lot simpler, a Discord user made a script (with the help of AI) which takes the scrambled .jpg image and the tag (e.g. 3,4,7,14,0,13,12,11,6,10,2,8,15,5,1,9) and then uses ImageMagick to unscramble that image. Then I may have to edit the image manually (the edges for example are not scrambled so I have to edit those in)

I'd love to share the script with those who use Honto and would benefit from it, just gotta know if it's alright with this community

Have you made sure it can't be gotten from Anna's Archive before you go the bother of cracking this?

Probably, but just checking.

Doesn't look like it. The book is quite recent (2020)

Digital Restrictions Management

Isn't it "digital rights management"?

What "rights" are there in the first place? This measure hurts the customer in the long run
