Kama (First Ascension) (Fate) Wiki

Kama in her First Ascension outfit from Fate/Grand Order. She is in her child form here, having short white hair with a pink ribbon tied on the left side of her head like Matou Sakura. She wears a purple halterneck top that becomes see-through around her abdomen, tight purple sleeves, a purple skirt, purple thighhighs, and gold high heels.

Note that her halterneck top is the same in her Second Ascension. The best way to tell them apart is that the First Ascension outfit has the dark skirt beneath the top's sheer part, whereas the Second Ascension outfit has a gold metallic bikini bottom.
