Tsutako Tomioka was the older sister of Giyu Tomioka. Tsutako was a dark-haired young woman with light skin. She wore her hair in a thick braid tied with a light-colored ribbon down her back and a loose fringe over her forehead. Her eyes were a shade of dark blue similar to her younger brother. She was seen wearing a dark red kimono and hakama tied below her chest. While little is known about Tsutako, she appeared to have been a courageous and loving sister, evidenced by Giyu Tomioka's guilt and sadness over her sacrifice. She loved her brother dearly enough to save him with her own life, even despite being set to wed the next day.
