Heya xellosp, I super appreciate all the help you've been giving to us here! I got a new error I don't think anyone else has got so far. Running 0_download_json.cmd and putting in the XSRF_token and the session values gives this error now:

Download kamihime info...
1.json already exists
https ://r.kamihimeproject.net/v1/characters/2
Token incorrect or has expired

Do we have to use a different token or cookie value now?
