yes, she's from same group - because they all are based on horror cliches Von Lycaon is a Werewolf Rina is a Poltergeist Corin is Frankenstein's Monster and Ellen Joe is Jaw's shark! and yeah - the advertisement is very... weak for this game, in spite of mihoyo literally paying money to people and channels that arent even gacha related
I just realized I'm over the trope of "attractive woman can't cook. also doesn't realize it. tries to force other people to eat her cooking but no one tells her cause she's attractive."
It's usually not because attractive but because "she tries so hard" but yeah that trope is very overdone. PGR has a little spin on it cause the girl who is like that actually improves and can now cook edible food. Pretty refreshing cause it's always a constant "can't cook at all and won't improve ever" thing.
