Yuba is mentioned as one of the 8 candidates for Fūjin by Jin. Yūichi Jin referred to them as "Yuba-chan", implying closeness.
- "Takuma" (拓磨?) is written with 拓 ("expand, open up, support or push"?) and for 磨 ("grind, polish, rub or wear out"?), while "Yuba" (弓場?) means "bow place".
- As -chan is typically used for young women and children, Yuba may be a young woman or a child of either gender. However, "Takuma" is a typically male name.
