Yuki Mizutsuki

Yuki Mizutsuki (由紀水の月, Yuki Mizutsuki) is Jonin-level kunoichi from Konohagakure, a medical-nin, and a member of Team Mizu. She has a unique Kekkei Genkai, the Suishogan.

Background
Yuki was born into the old and rich Mizutsuki Family. The Family is one of the clans in Konohagakure. Unfortunately, Yuki's mother had not survived the birth. Therefore, only her father Ryo knew that Yuki was a girl. But Ryo needed a male heir, so he could remain the head of the clan. He exchanged his baby against his brothers. Samui was born almost at the same time and at the birth of Samui were complications. So Taki, the real father, stayed with his wife Mizumi. The baby was placed in the meantime in another room, where the exchange took place.

Yuki was only seven months old on the day the Kyuubi attacked Konoha, and she lost both of her "Fake" parents during the assault. Because of this she was taken in by her real father which the didn't know.
