Kurama Yakumo

Yakumo was the heir of the Kurama clan. A savant in Genjutsu she was the pride of her clan. When her parents were killed in a fire, she was turned over to Yuuhi Kurenai to watch over. Sandaime felt Yakumo's talents were wild and could bring about disaster for Konoha. Kurenai later felt she could not properly train the young woman, so her powers were sealed away and she was sent to a mountain retreat for her own protection.
