Yakumo Kurama

Yakumo is the last surviving member of the main branch of the Kurama clan, and as such, the heiress to the clan. She inherited the clan's kekkei genkai in its entirety, giving her the ability to cast illusions that are so powerful that they can actually produce real effects. She often uses paintings as a conduit to cast these illusions, causing reality to reflect what is on the painting. Born with a weak body, she was unable to perform the physical activities required of a ninja. Worried about this development, her father petitioned the Third Hokage to grant Yakumo a special tutor to allow her to become a proper ninja. This tutor was Kurenai Yuhi, who was a genjutsu user like Yakumo. Inspired by the example of Rock Lee, who was unable to use ninjutsu or genjutsu, and his relationship with his sensei Might Guy, Yakumo believed she could become a ninja through solely concentrating upon her genjutsu skills. However, Kurenai lacked Guy's optimism, and felt she was unable to train Yakumo in this regard. She eventually refused to train Yakumo, instructing her to seek another path in life. Yakumo refused, though, and Kurenai later sealed her powers. This was done on the order of the Third Hokage, as he had been made aware of the Id monster, a sentient, malicious personality within Yakumo that could control her and use her incredible powers to destructive means - with the destruction of Konohagakure foremost in his mind. However, the Idou monster overcame the seal, and cast an illusion of a fire engulfing the Kurama clan's household, which killed Yakumo's parents. Yakumo, however, believed that the fire was started on the order of the Third Hokage, having overheard a conversation that she believed indicated that the Third Hokage was planning to kill her if she became too much of a threat.

Seeking revenge on Konohagakure, and specifically Kurenai, Yakumo returned in an anime filler arc, where she trapped the entire village under an illusion of her own making. In the course of events, Yakumo eventually overcomes the Id's influence and kills it with her palette knife. After that, she finally makes peace with Konoha and her former teacher and is isolated in a mountain home.
