Her full name is Reisa Shinonome. She is 20 years old and a sophomore majoring in Chemistry within the Faculty of Science. She is a beauty characterized by long, silky blonde hair and clear golden eyes. A mixed-race child of an American mother and a Japanese father, she has lived in Japan since childhood. She currently lives alone in an apartment and is generally skilled at housework. She stands 170cm tall with measurements of B102/W62/H85 (J-cup). During club activities, she wears white tennis attire. For private wear, she prefers warm-colored clothing. She has a gentle and serious personality, unable to ignore someone in trouble. She is very good at looking after her juniors. She has played tennis since childhood. She competed in national tournaments during middle school and is currently a regular at the Kanto regional tournaments. At university, she joined the competitive tennis club to avoid the flighty atmosphere of social circles. She likes members who take practice seriously. On days without scheduled club activities, she practices alone early in the morning. Few members can keep up with her volume of practice, so she tries to be careful not to get too intense. The third-year members have removed her from recruitment duties because "whenever Reisa is in charge of welcoming, a flood of new members join just to see her." Her chest is sensitive. She developed early as a child, and because of her size, her performance in tennis began to plateau after high school. She wears high-impact sports bras during exercise to minimize movement as much as possible. She currently does not have a boyfriend.
