[[bb (swimsuit mooncancer) (fate)|BB Swimsuit MoonCancer]] in her Third Ascension swimsuit from [[Fate/Grand Order]].

Her hairstyle returns to normal, but the hair length grows significantly longer. She wears a black vampire-styled coat with a large popped collar, a [[white leotard]], a red bowtie, [[white gloves]], and red [[high heels]]. She is also accompanied by a series of demonic black, red and yellow tentacles [spoiler]due to the connection she made with Nyarlathotep[/spoiler]. She always wears this Ascension's swimsuit during her Noble Phantasm, Cursed Cutting Crater, although she is more playful in her first two Ascensions while she is evil in this one.

This tag can include her tanned and non-tanned variants.
