Ok but hear me out, the vampire Carmilla? who turned into a cat? elegant? only drank from her lover’s left breast?
If I could write ship fics this would be the perfect Momojirou au. Come on.
You either have Momo the lesbian vamp, smitten with the beautiful young Jirou who swoons at the attention of the most beautiful women she’s ever seen.
Or high class Momo who waits at the balcony for her mystery shrouded lover to visit each night, Jirou having stolen her heart long ago and promising to steal her away into the night.
