The free version only contains the first 4 characters, but the paid one is the full game, with all the characters I've listed in the description.
There is also a Zip file with a different price, which is a Zip file of all NSFW images I have for Genshin Impact characters, categorized (I didn't put all of images I have in game, because I have A LOT :)))
You can also have access to these content as well as Futa Moderator and much more stuff, through my Patreon as well, however you feel more comfortable ;)
