The Woshu Woshu no Mi is a Paramecia-type Devil Fruit that allows the user to literally "wash and hang out to dry" people and objects as if they were clothes, making the user a Laundry Human (洗濯人間 Sentaku Ningen). It was eaten by Tsuru.
The main strength of this Devil Fruit is that it allows Tsuru to "wash and hang out to dry" people and objects as if they were clothes. This seems to render her victims unable to fight back or move. According to Oda, "villains who have been dried get their hearts a little bit cleaner as well; their evil hearts become fainter, so that's a dangerous ability against pirates".
