The "lewd patcher" just means "you have to download the lewd pics separately." If you're on the JPDE Discord you can find the lewd pic files there, or there's a non-discord link to those pics... somewhere. Not sure where, but I know that they aren't just a "Discord Exclusive" thing. Anyway, once you download the lewd pic files, extract them, then replace the blank pics with the actual lewd pics. And, to actually activate the lewd content, you need to use your scroll in-game and call a "certain number" and ask them to enable 18+ stuff.
