Looking for help searching a game

Hi guys, i am searching for a game I've seen some time ago of which i have forgot the name. I remember it being made with RpgMaker, where the mc is a guy with a party of women adventurers (one of them is a nun/priest or religious girl i think) and suddenly another girl, who's is a friend of them, comes to their house and thanks to her newfound eldritch goddes power and her robe, inside of which there are eldritch tentacles that corrupt and mind control the girls of the party, and then she reveals her new identity to the mc. Here the mc accepts to work with this eldritch goddess that gives him powers to save the world from some kind of other threat, while transforming back the girls to their original form, and leaving the mc with also the power to slowly corrupt all the girls like the eldritch goddess. Any help is more thank welcome 🤗
