It doesn't appear this is as easy as I'd hoped. I went on DMM attempting to acquire relevant original scenes and it appears the game will refuse to send me the relevant JSON files unless I have the character in question for that scene.

Example output when requesting Phoenix's data:
Code:
{"errors":[{"id":"","message":"forbidden","code":"40301","trace":null}]}
- - - Updated - - -

Here's the opening scene for Adele, this is about all I can do for now. There isn't much else I can do about obtaining the original text.

(apparently I still can't post links)
