Nikki was born in Tokyo, life there was much different there than anywhere she had been before. She was a quiet, nerdy girl who just wanted to live and went by whatever presented itself. She had a pretty quiet life where she was until one day a surprise vacation turned for the worse. While vacationing in the city of Chernogorsk, a group of thugs kidnapped her and her friends, stole their belongings, demoralized them, and taunted them. They felt something for Nikki though, they decided to murder her friends and sedated her. When she woke up she was unable to talk. When the outbreak struck the men decided the would have her travel with them and use her as they pleased. One night when everyone was sleeping, Nikki noticed one of her cuffs was loose. She was able to get her hand out and untie the rest of her self. She then took a pistol from the men and put a bullet in some of their heads, when the lookout ran into the room and tackled her down, she bit his neck with all her strength and bit through it. He died shortly after, after ingesting some of the mans flesh, she sympathized with the infected and struggles to resist the hunger while caring for both living and dead. She now roams, doing as she sees fit.
