Mito Uzumaki

was a kunoichi who originated from Uzushiogakure's Uzumaki clan and later married into Konohagakure's Senju clan. She was also the first jinchūriki of Kurama, the Nine-Tails.

Background
The Uzumaki and Senju clans, being distant relatives, always had close ties. Mito ended up marrying Hashirama Senju, who would help found Konohagakure and became the village's First Hokage.

During her husband's battle against Madara Uchiha at the Valley of the End, Hashirama at some point gained control of Kurama. To gain power for Hashirama, Mito used a fūinjutsu to seal Kurama within herself, becoming the tailed beast's first jinchūriki. Despite the seal's strength, it almost broke at some later point when she was going through childbirth. Eventually, her husband died in war, and Mito was left a widow.

Towards the final years of her life, it was decided that a new host for Kurama would have to be found. Kushina Uzumaki, one of Mito's clansmen, was then selected for the role due to her special chakra, and was terrified by the idea. Mito comforted her however, and before the transfer was performed, told Kushina that love was the only way to counter Kurama's hatred.

Appearance
Mito had long, bright-red hair and large, pupiless eyes. She wore an elaborate, high-collared kimono with the Uzushiogakure symbol on the back of the obi tied around her waist. Her hair was arranged in buns with hair pins in them and three clips in the front. She also wore a dark shade of lipstick and had a diamond mark on her forehead, similar to that of her granddaughter Tsunade. She also wore what appeared to be seal tags in her hair decals. In her old age, her hair had grown much longer some of which she allowed to hang into her back and — as the anime showed — became dark brown in colour. She however maintained the two buns in her hair and wore a simple loose fitting kimono held closed by a simple dark-coloured obi.

Abilities
Not much is known about her fighting skills, but Kushina hailed her as a powerful kunoichi. She was shown to be exceptional at fūinjutsu, being able to seal the entirety of Kurama within herself. Also, due to being a member of the Uzumaki clan, Mito had an exceptionally long life, having lived through the reign of the first three Hokage. Like Naruto, Mito also had the ability to sense negative emotions due to her control over the fox's power.

Trivia
