Uroko Kurama

was a minor background character during the anime-only 'Kurama Clan' filler arc in part I. Uroko Kurama was a member of the main branch of the Kurama clan; She was also the wife of Murakumo Kurama and the mother of Yakumo Kurama.

Uroko's daughter and only child, Yakumo, was born with the full scope of the Kurama clan's kekkei genkai, but also with a weak and frail body. As the Kurama clan had produced few ninja where once they were one of the more prominent clans in Konohagakure, Uroko's husband Murakumo was eager to remedy this predicament sought to change the clans fortunes around by ensuring their daughter's development into her full potential as a Genjutsu-user. Her husband approched the Third Hokage and petitioned for a special tutor to over-see her training, hoping that she could overcome her frail condition by focusing sorely on her genjutsu, (much like the situation with Rock Lee).

Later, a fire engulfed the Kurama clan's household and killed both Uroko and her husband, Murakumo. The cause of the fire was Yakumo's own powers; because of the powers she could not control, Ido, an independent, sentient and malicious personality that existed within her subconscious could use her powers against her will and started the fire. Uroko's daughter Yakumo, however, unaware of the Ido existence was initialy convinced that her parents were killed on the orders of the Third Hokage, Hiruzen Sarutobi, before learning that the deaths of her parents was due to the Ido.
