Rena Ashihara  

, 葦原 怜那

The Takenaka twins were first introduced to her with a boastful attitude and won a basketball game in which they played together. Although the agreement was meant to be private among themselves, dealing with her has become a matter of concern for the entire team, especially Masami, when she made an error during the food festival. She is skilled at playing 1-on-1 basketball but struggled with 5-on-5 during a crucial tournament against Keishin, who was on the opposing team.
