You're welcome for the help. The contents of the booklet are in Japanese.
Your best chance of finding the booklet online is to purchase the Luminous Avenger iX CD since I do not have it.
I'm sorry, but no I don't have scans.
It's stated in the Luminious Avenger iX OST booklet Asimov extracted the septimal inducers from Gunvolt's and Joule's bodies after having killed them. He would then go to implant them into Blade and Mytyl aka the Butterfly Effect.
I agree with all of the points you made in your post. Excellent job!
