The purple haired survivor

Young ten year old Umeko witnessed the murder of her clan, the Kurama clan known for the ability to cast illusions that are so powerful that they can actually manifest real effects making genjutsu to be completely irresistible. Allowing the user to potentially kill their opponents with genjutsu. As a drawbacks the user can rarely control the full extent of this ability, and as such their subconscious will often regulate that power, leading to the creation of a second personality in control of that power. This personality then overwhelms the original, turning the individual into a monster that's a danger to everyone around them. She wished revenge on the one who murdered her clan Orochimaru of the legendary sannin.
