SteppyIsWeird

Recently, i've found a few old screenshots of it with 3 characters, the fl/protag has purple hair and eyes, her brother with brown hair and a father with over 30 wives

I think its one of those " Adopted by the demon lord " tropes, but can't remember much, just know that it was a bit of comedy

Read this 2 years ago and i'm unable to find it anymore, please help ;-;
