Miss Thursday

Miss Thursday (ミス・サースデー, Misu Saasudee) is the Partner to Mr. 11 and a Frontier Agent in the Baroque Works rankings. Even though she and her partner Mr. 11 are part of the number agents system, her rank partnership (higher then 10) makes her not much stronger then the Billions.

Even though her partner Mr. 11 makes an appearance in the story, she is never seen herself.
