@KareenCelestin Well to be fair, in the orignal Japanese Haku states "I am a man." Despite this Haku is revealed to be around Naruto's age. Meaning the age was a lie. Haku also admonishes Sakura purely for her gender remarking how women aren't needed in the ninja world. Haku even speaks about casting aside all that he/she is in order to serve Zabuza, in the world where he/she just mentioned women don't belong. Because of this, I and some others online believe that Haku is in fact a female, pretending to be a male so she will be taken seriously in the ninja world.
