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).

Personality
A veteran marine who is not without wisdom for her age. She seems extremely knowledgeable; she knew who set the Marines to fight each other in the Marine and Shichibukai meeting when all others thought the two were simply messing around, and knew who Lafitte was on sight. She is not above telling off the younger marines that show concern for her well being when she steps up to fight the incoming pirates at Marine HQ. She then justifies her being on the front line with the other Vice-Admirals by stating there is no longer a safe place left in the world for her to run to anyway.

Abilities and Powers
Tsuru is a Marine who is well skilled in strategy. She apparently ate a Devil Fruit that allows her to literally "wash and hang out to dry" people and objects as if they were clothes.

Jaya arc
She was present for the gathering of the Shichibukai to choose a replacement for Crocodile.

Marineford arc
She was next seen in Chapter 550 at Marineford, saying comforting words to Garp concerning the upcoming execution of Portgas D. Ace. Then when Whitebeard arrived she commented on the illogicality of his position, and faced along with the other Vice-Admirals when Whitebeard's division commanders began their attack. Although Vice Admiral Yamakaji expressed concern for her safety during the attack, Tsuru stayed at the front lines, stating that she was as safe there as anywhere else.

Anime and Manga Differences
Although in the anime she doesn't say anything, in the manga she talks to Donquixote Doflamingo, ordering him to be a good boy and 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."
 * She is the only Vice Admiral woman and the highest-ranked female in the Marine seen this far.
 * She was introduced as Marine headquarter's second in command despite being a Vice Admiral. Whether she holds more power than an Admiral is unknown.
