Tsuru

Vice-Admiral Tsuru (つる中将 Tsuru Chūjō) the "Great Tactician" is one of Sengoku's direct subordinates at the base in the Sanctuary of Marie Joie. She is an elderly woman, similar in appearance to Dr. Kureha, but older-looking (and probably younger). She was present for the gathering of the Shichibukai to choose a replacement for Sir Crocodile.

Anime/Manga Difference
Although in the anime she doesn't say anything, in the manga she talk to Donquixote Doflamingo, ordering him to calm down

Trivia

 * Eiichiro Oda has stated that he tends to name female characters after birds. The tradition continues with Tsuru, whose name means "Crane."
