Voyage: Has the Gender Changed?

When Hodder woke up, he found that he had traveled to the world of One Piece and became a soldier under the command of the Four Emperor Kaido. However, this is not the point. The point is that people in this world are all gender-reverse! Kaido, Whitebeard, Shanks, Luffy, Hawkeye, etc. Have all become women, Sherlock Lingling, Nami, etc. Have become men... Where is the world of One Piece? Is this the world of the female pirate king? Hod is numb... This novel and its characters are purely fictitious.
