@Matla She lived 800 years ago, didn't you pay attention to the dialogue?

@Ergotth and? if there is a hole there is a goal and my guy dragon knows that better than anyone

@Ergotth  
Well there is a possibility
Like 
Imu could be a woman 
Imu could be in a young female body 
Imu could have met dragon by chance
Imu could have had given birth to luffy and then left both of them
