osakabehime (swimsuit archer) (first ascension) (fate)

Osakabehime Swimsuit Archer in her First Ascension outfit from Fate/Grand Order. She wears a set of goggles on her head, a black and purple coat, a blue striped scarf, black gloves, black shorts, and black platform sandals.

If she has her coat open and is wearing the bikini from her second ascension, she's actually in her final ascension costume instead.
