Haku

- Haku in his shinobi attire. - Haku in his casual outfit. 1/2 Haku was a 15-year-old boy with an androgynous appearance and was even viewed as being beautiful by Naruto, who exclaimed that he was "prettier than Sakura", even after he informed him that he was male. He had long black hair, pale skin and large, dark-brown eyes, and a slender frame. Haku's normal shinobi outfit consisted of the standard Kirigakure pinstriped outfit which stopped at his knees. Over this he wore a green haori with white trimmings, and around his waist a brown sash with a fringed trail wrapped around his waist twice. He also wore light-brown platoon sandals with straps in the same colour as his kimono and nail polish on his fingernails and toenails in matching blue green colour. When wearing this outfit, Haku's long hair was gathered in a white bun holder, while two locks of his hair fell loose framing his face, bound with metal hair cuffs at the ends. Haku also wore a black forehead protector with the Kirigakure's symbol upon it. When in battle or moving covertly, he wore a hunter-nin mask on top of his forehead protector, which was white with thin, curved eye-holes and a red wavy design in place of the mouth, as well as the Kirigakure symbol etched in the top. When Haku was not in combat, he wore his long hair loosely, and wore a pink, sleeveless kimono, with pale red edges and decorated with small plum-coloured swirls, that went to his ankles. Around his waist was a simple white obi tied in a bow, and he wore a pair of light brown sandals with dark straps. He also wore a dark-coloured choker around his neck. When he was a child, Haku wore an overly-large, shredded light-brown shirt which fell off his shoulders, and a pair of shredded knee-length pants, as well as the dark choker. Later when taken in by Zabuza, Haku was spotted wearing a short blue kimono with light blue edges and a dark grey split skirt, similar to those ones he wore as a shinobi, and also similar to those he wore as a younger child when his parents were alive. When he was reincarnated, his sclera turned black.

Haku was born in a small, snowy village in the Land of Water, a land that had suffered from war not long before. In this war, different sides battled each other using ninja, some of whom possessed kekkei genkai. After the war ended, memories of the horrific battles still lingered in the minds of the people. Those with kekkei genkai quickly became feared and hated for their abilities, out of concern that their existence would only bring about more war. Haku's father and mother were simple farmers, and they lived a peaceful life. They loved each other, and were kind to their child. Unfortunately, this would all change. Haku's mother was a wielder of a kekkei genkai: Ice Release. She hid this fact from her husband, hoping that the love and peace that was shared in their small family would last forever. One day, Haku discovered the ability to manipulate water. Amazed by this, Haku proudly showed this to his mother, who was horrified by what she saw. She harshly scolded and slapped Haku for displaying his ability, though she tearfully apologized to him immediately afterwards. Unbeknownst to them, Haku's father had seen everything from the shadows. When Haku's father discovered that his wife and child possessed a kekkei genkai, he assembled a small mob of villagers. With tears flowing down his eyes, he killed his wife. He then attempted to kill Haku. But before he could, Haku used his Ice Release to create several large ice spikes to kill his father and the rest of the mob. Orphaned, Haku became a child who was wanted by no one and was forced to take to the cold streets and rummage through trash bins for scraps of food, even sometimes having to fight off the wild dogs that roamed the streets. In time, he was confronted by Zabuza Momochi, a man who had "the same eyes" as him. Zabuza later asked Haku to become his "weapon," which meant to become a dedicated shinobi for Zabuza. Haku readily accepted this role, due to the purpose it gave him, and devoting his life to becoming the ultimate tool for Zabuza to use. In the anime, upon leaving the Land of Water, Haku and Zabuza met Kimimaro. Haku appeared to sympathise with Kimimaro for his loneliness and lack of purpose by looking into his eyes. However, he was forced to keep moving by Zabuza, and left Kimimaro to be. Zabuza then trained Haku in the ways of the shinobi, as well as every fighting technique that he knew.
