Tsukihime Umaki is male. She was adopted by her uncle Carl Heinz (Tougo Umaki) when she was a child. She is the last son in the family and has six older brothers. When he was four years old, he met Yukimura Seiichi and Sanada Genichiro at the tennis club. He was emotionless and didn't understand the boys' love and excitement for tennis. He thought it was very boring. The two refused to admit defeat and made a promise with Tsukihime that tennis is not boring. They came to Rikkai University to join the tennis club and witness all this.
After the bet was fulfilled, he started practicing tennis. Later, due to Cordelia, his memory became confused. When he woke up, he forgot everything. He seemed to remember that he had made a promise with someone to join the tennis club, and gradually began his own tennis journey...
Intention: to miss
