Haku hah Extremely androgynous in appearance, actually Haku is a guy, very unfortunate ... but very cute Haku and more suitable as a girl. Haku's mother was killed by his father after he had found out about her genetic ability. He would have killed Haku Haku as well if had not beaten him to it.
Because of this traumatic experience, Haku could not find purpose in life ... until he met Zabuza Momochi, Haku who found useful as his "tools". Haku has the ability to manipulate wind and water in his surroundings to make ice. However, he does not like fighting and often uses his ice needles to pierce the opponents pressure points to leave them in a dead-like state.
and he has Bloodline Ninjutsu, which forced users to exceed the human limits. as Saringgan which is owned by Uchiha clan.
Poor Haku. His story really makes me sad, even though I've only read it in the manga. I wish he stayed in the series a lot longer ... and he's quite suitable as Haku cosplay though ... Brilliant!
