In SAO, Nijika's avatar was a reflection of her in real life except she changed her hair color to red, since she always wanted to have red hair. She always wore a white blouse with a black overcoat. Below, she wore a black skirt with gray leggings and at her belt her two swords hung.

Personality
Nijika is a shy girl, shown in the fact that she constantly spied on others.

Background
Before logging into ALfheim Online, Nijika lived a happy life with her parents and younger sister, Nanairo Arshavin (Seven), in Russia. However, when it became apparent that her sister's genius was blooming, her parents argued about the future they wanted for her, their father wanting to nurture her genius, while their mother wanting her to live a normal life. The family eventually divorced, with Nijika moving back to Japan, while her father gained custody of her sister, who had forgotten all memory of her mother and sister as she grew up in America.

While living in Japan, Nijika became infatuated with pop culture and had a part-time job working for a maid cafe in Akihabara. She dreamt of becoming an idol to one day stand alongside her younger sister with pride. Despite the love for her younger sister, her sister's success sparked jealousy in her heart. Nijika eventually became one of the 10,000 victims of Sword Art Online (SAO), and survived the game on her own. In the aftermath, she met with Kikuoka Seijirou, whom she asked for information regarding her younger sister.
