A second year at Crimson Field, Tomoyo was known to be a star volleyball player in junior high until she suffered an injury during a game and was forced to take a break. She resolved that she should no longer play volleyball, despite the fact she is considered a "genius setter" on the court. After a lot of persuasion, Tomoyo joins Nobara's team as the sixth member required to form the team. After Yui's departure, she is elected team captain. She has previously dated Keisuke and still has feelings for him, though she also knows that he likes Nobara.
