Firstly I can't believe Imu came all these way just because of usopp which is kinda funny 🤣👍🤣, secondly I believe his thin shadowy body is a saving mode so that he doesn't get weakened and thirdly I think he has the ability to change genders if not why you explain the male and female voice overlapping on each other either that or Oda just did it to mess with us so we would be guessing the gender from the beginning
The line between fiction and non fiction are blurry
