Origin
Kirigakure
Ruka is a kunoichi of Kirigakure. While having a quiet, reserved demeanour, Ruka is fiercely loyal to her village and equally so to her comrades as she spoke out against Pakura's tirade against Kirigakure telling her that the Fifth Mizukage would usher in a new era for the village while worrying about the safety of her comrades.
Naruto
Moments prior to Naruto Uzumaki's birth, a huge demon known as the Kyuubi, the Nine-Tailed Fox, attacked Konohagakure, the Hidden Leaf Village, and wreaked havoc. In order to put an end to the Kyuubi's rampage, the leader of the village, the Fourth Hokage, sacrificed his life and sealed the monstrous beast inside the newborn Naruto.
