Fate character. BB as she appears in Fate/Extra CCC and as a 4-star MoonCancer-class servant in Fate/Grand Order.
Appearance-wise, she looks like Matou Sakura, with long purple hair and purple eyes. Her normal outfit is a Dracula-like black coat with a high collar, a white shirt with a large red neck ribbon, a black high-waist skirt (that emphasizes her large breasts), and thigh boots.
There are slight differences between the design in Fate/Extra CCC and Fate/Grand Order, with CCC featuring lace trim on her thighhighs in contrast to the slits on her Grand Order thighhighs, and the Grand Order design featuring the moon cell logo on her coat.
Not to be confused with BB (Swimsuit Mooncancer) (Third Ascension). Both wear a similar black cape, but BB (Fate/Extra) wears a sleeved shirt with a high-waist skirt, while BB (Swimsuit Mooncancer) wears a white halterneck leotard.
This tag is for her costume introduced in Fate/Extra CCC. If she's wearing a different costume, do not use this tag.
