Yakumo Kurama

is the last surviving member of the main branch of the Kurama clan, and, as such, the heiress to the clan.

Background
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 simply 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, however, and Kurenai later sealed her powers. This was done on the order of the Third Hokage, as he had been made aware of, a sentient, malicious personality within Yakumo which could control her and use her incredible powers for destructive means - with the destruction of Konohagakure foremost in his mind. However, the monster overcame the seal, and cast the 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.

Abilities
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 manifest real effects. She often uses paintings as a conduit to cast these illusions, causing reality to reflect what is on the painting.

Kurama clan arc
Seeking revenge on Konohagakure, and specifically Kurenai, Yakumo escaped from her mountainside manor, which was under constant surveillance by ANBU and medics. She traveled to Konohagakure, and painted a picture of lightning hitting the Hokage's mansion. As the lighting struck and the mansion began to burn, she packed up her supplies and left. However, she didn't get very far before a squad of medical ninjas and an ANBU intercepted her, knocking her out with a sleep-inducing drug. Naruto, who had been following her after seeing her painting, was warned to stay out of their way before they returned to the manor. A few days later, a group of her clan members, led by her uncle, Unkai Kurama, attacked the manor. Kurenai Yuhi trapped the clan members in a genjutsu until faced by Unkai Kurama. While Kurenai was fighting Unkai,Might Guy came to the spot with the squad 8 members,Sakura Haruno and Naruto Uzumaki.With the assistance of Hinata Hyuga's Byakugan, Naruto managed to defeat Unkai Kurana.He swore to get Yakumo back as he fled away.
