In the first round of the inter-high qualifying rounds, she led Sanae to victory with sound advice. On the other hand, she is also very strict, for example, forbidding randori when she is not present and forbidding Anna, a beginner, to participate in the Kin Shuu Ki competition. She went to high school at Tachikawa Academy and played volleyball as a student. While there, she was voted "Mr. Tachigaku" three years in a row, beating out all the other male students at the school.
