The Dorei Dorei no Mi (dorei being the Japanese word for servant) is a Devil Fruit that allows the user to enslave anyone under his will, as long as the fruit is of the opposite gender of the user.
The most obvious strength of the fruit is that the user can bend the mind of anyone close to him to make them his slaves, but it only works on people of the opposite gender. What could be considered the greatest strength is that it requires no activation; the powers are always active, rendering anyone close to him helpless.
Weaknesses[]
The most glaring flaw of the fruit is that while it can bend the will of any one of the opposite gender, it only works on people of the user's race; therefore, if a human consumed it, giants, fishmen, merfolk and various other races will remain unaffected. Also, if the user is knocked unconscious, everyone he has bent to his does him every whim will spontaneously be freed from their hypnotic trance.
