A sister of an internationally acclaimed hip hop artist, Emmanuel Jal, Nyaruach was born around 1983 in Southern Sudan, at the time of the civil war. She lost her mother and was separated from the rest of her immediate family, including Jal, at the age of 4. As years went on, the war intensified, and the orphaned girl was forced to run around with her relatives. She witness her family members killed, houses burned and women raped. Her brother meanwhile was fighting as a child soldier. Seeing the effects of war from such an early age, Nyaruach has suffered post-traumatic stress. But it wasn't the worst of her torments. Between the ages of 9 and 13, she was raped several times by government soldiers.

There was little hope in her life until she reunited with Jal in 2004 in Nairobi. The two recorded a song together called Gua, which stands for "peace" in their native Nuer tongue. The track was broadcast by BBC across Africa and became a No. 1 hit in Kenya in 2005. It was also Jal's breakthrough to the international market, earning him a spot on Bob Geldof's "Live 8" concert in the UK.

Nyaruach kept her past to herself for a long time, but in 2008 she stepped over her personal pain and revealed her shocking story in War Child, an award winning documentary on Emmanuel Jal's life.

Through her story Nyaruach wanted to emphasize the importance of educating girls in particular and children overall. She believes that the future of her native Sudan and Africa as a whole can be enhanced by education. She believes education is the only way to a free Africa.

Because of the unbearable trauma in her life, Nyaruach was a troubled child, and was suicidal for a long time. Her life has gained meaning, however, as she joined the campaign to help her brother build a school in Southern Sudan. She made a commitment to stop eating breakfast until the money for the school is raised. Nyaruach said being in the studio and recording music became the happiest time in her life. Her first single, Gatluak, became available on iTunes in March. A mixtape under the same name was released by Gatwitch Records in September. The artist is in the final stages of recording her first solo album, and part of the proceeds from her music will go toward the building of the school.
