She effectively isn't blind seeing as she just uses echolocation in place of her eyes, I personally wold only date her if I liked her, I already have tinnitus so the screaming isn't something I care about, and I'm not so insecure about myself that I feel the need to date a blind chick, which I assume is 90% of the chuddies falling fur this sisarald.

if your bat girlfriends wings aren't a part of her arms AND at least the size of her body then can she even be considered a bat girl? this is just a blind succubus with bat ears and fur.
