Uroko Kurama

Uroko Kurama was a member of the Kurama clan and the mother of Yakumo Kurama. Her daughter believed for quite some time that she was killed on the orders of Hiruzen Sarutobi, and began to carry a loathing for the kage. Yakumo later found out that Uroko was killed by the monster inside of Yakumo, which caused the fire.
