This is my own series based on asks sent to my CuriousCat (https://curiouscat.live/Vhiel) and posted on my Pixiv (https://www.pixiv.net/en/users/14490626) as well as the official Discord for my game, Odyssey of Gianna (https://discord.gg/B5JwPBa). Though the versions uploaded to Pixiv have to be censored, the originals posted on the Discord aren't, so these are uncensored.
Kinda curious, but what about just having your thoughts and identity just slowly being replaced by someone else's? Like possession, in the end it would just be an invader to your body being in control of you and being able to know your darkest and deepest thoughts and able to use it to either take advantage of what you've built up or just humiliate you and let you either remember the entire process or that you'd only feel the aftereffects. Which one would you prefer?
