I mean, if you'll accept Zero Two from Darling in the FranXX, I can easily have their appearance be explained away as "oh another Japanese cosplayer." And no one thinks to question why she still has horns when she removes the headband. Also debating if I'll have her only remember her kinds native tongue, or if she'll still know how to speak English. Her native language is basically a mix of latin and icelandic, so have fun with weird wordings. I'll be working on the CS in the meantime!
