Hinako attends in an all-girl school and grew to value sumo's techniques after watching a professional match. Hoping to practice along with her classmates, she tries to create a female sumo club at her school but the idea fails to gain support.
Once she hears about the Women Team auditioning for a member, Hinako enters and succeeds in proving her worth by defeating Yuri Sakazaki in a mock match. She continues to appear for their team until The King of Fighters 2003 where she was asked to team with Athena Asamiya and Malin to form the "High School Girl" Team.
Hinako is a kind girl who wishes to prove that girls can also practice sumo. She is somewhat shy, but also a very loyal friend. Although her blond hair and facial features indicate her Russian descent, nonetheless she considers herself to be purely Japanese.
- she in also shares of Date of Birth by Taokaka in BlazBlue and a Kanon Nakagawa from the The World God Only Knows.
