lets hope that the characters them selves are not copyrighted if so you forcing people to pay will result in a lot of legal issues on your end
Viewing post in Training Slayer comments
First of all..this ain't twitter. Second of all..Suing a NSFW game with literal naked women would be the most shameful thing someone can do. Imagine you see on news "A sex game called training slayer got sued by the author of demon slayer" PEOPLE WOULD LITERALLY STOP WATCHING DEMON SLAYER OUT OF SHAME LMAO..PEOPLE WOLD HATE THE AUTHOR
not really Pokémon did something similar a few years ago though it never really went public because it was mostly a hush hush thing, lots of anime creators don't like people using their characters for something other than what they was meant for, NSFW pictures are one thing completely harmless and not profitable nsfw games however are a completely different ball game it all has to due with copy right infringement, demon slayers creator may or may not care who is to know and this case would probably be hush hush as well there was a few incidents where popular anime's got nsfw games that people was paying for and the creator found out and sent a cease and desist for copy right issues.
