Introduction
Mito Uzumaki (うずまきミト, Uzumaki Mito) 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, Due to being a member of the Uzumaki clan, Mito had the potential to live an exceptionally long life. This was seen in part from her having lived her adult life 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
Some time after this, the beast was presumably extracted from within Mito and sealed into Kushina, resulting in Mito's death.
