Woshu Woshu no Mi in One Piece

At some point in the past, the Navy Vice Admiral Tsuru devoured the Woshu Woshu no Mi (Wash-Wash) Devil Fruit. The fruit’s appearance has not been revealed.

This Devil fruit’s main strength is that it allows Tsuru to “wash and hang out to dry” individuals or items as if they are clothes. Her victims appear to be unable to fight back or move as a result of it.

According to Oda, “Villians who have been dried get their hearts a little bit cleaner as well; their evil hearts grow fainter, so that’s a dangerous ability against pirates”.

The fruit has no known weaknesses besides the standard Devil Fruit weaknesses.

Tsuru has so far been seen using this power to disable pirates. She can also “clean” a certain quantity of evil from the hearts of her opponents, making them slightly less bad. It is unknown how she uses her abilities.

Q. What does the Woshu Woshu no Mi do?

A. Woshu Woshu no Mi is a Paramecia-type Devil Fruit that allows its user to literally "wash and hang out to dry" people and objects.

Q. When did Tsuru consume the Woshu Woshu no Mi?

A. It hasn't been revealed, but Tsuru presumably consumed the fruit at some point during her youth.
