Miss Saturday

Miss Saturday (ミス・サタデー, Misu Satadē) is the partner of Mr. 12 and a Frontier Agent in the Baroque Works rankings.

History
She was first mentioned by Nefertari Vivi, who explained how Baroque Works was organized to the Straw Hat Pirates. Even though she and her partner Mr. 12 are part of the number agents system, her rank partnership (higher than 10) makes her not much stronger than the Billions. Neither she nor her partner are seen in the series.
