Shiro was a shy but strong-willed woman, devoted to her friends and comrades despite her lack of self-confidence. Due to almost being sacrificed early in her life, Shiro was traumatized by the experience and developed a nervous temperament.Over time, however, Shiro's courage grew as she learned how to become a sniper; as a result, the Netsuma drew confidence from her shooting skills and would become more bold every time she held a gun. She often stammers and apologizes whenever spoken to.
