kama (third ascension) (fate)
Kama in her Third Ascension outfit from Fate/Grand Order. She is in her young adult form here, having long hair and a pink bow tied to the left side of her head like Matou Sakura. She only wears gold shoulder pads with a purple cape attached to them, a gold metallic bra that only covers the sides of her breasts, and a gold metallic bikini bottom. Her arms and legs are charred black and glowing with bright blue flames.
Kama's Beast III/L form borrows from this Ascension, but her coloration changes and she gains a set of horns depending on which Beast form she's in - either her Kama/Mara form, or her Demon Lord of Lust form.
