I just thought about it while I was fapping to a photo of Bernadetta tied up, but she really does look similar to Haruka.
Hours spent grinding those pitcher plants feels the exact same now that I'm doing with Haruka and her flytraps.
Even similar predator plant interests
Not to mention their insanely shit self esteem, that gets better after having a relationship with (you) as their teacher who loves and cherishes them regardless. (Ps68 helps a lot with her too, but still) Just that Haruka isn't a shut in who got raped by her uncle. While Berna isn't a psycho who loves to bomb places either.
Probably why I was so enraptured by her when I first started BA. She's the objectively better character now, but I still like both

Shame fe3hrt sucks ass as a game and it created dogshit characters like edeltard with a fanbase as annoying and retarded as migger's.
