Found a way to acces FullFlap/tetsujinex's paid content on Ci-En that allows paypal and credit cards used in Europe/Usa. https://ci-en.dlsite.com/creator/1041/article?mode=list&page=3

You can buy dl points cards on this adress: https://forbooks.jp/en/products/dld003p
It usually takes 2-5 mins to receive the code.

Then when your code arrives in your email, Ci-EN allows you to use dl site points to pay for stuff on there.
Enter your gift card code to get the points then you can spend them to get previous issues they posted!

Holy based, Batman!
