Rena Ashihara
She first made herself known to the Takenaka twins with a braggart swagger and beat them in a 2-on-1 basketball game. The deal between them is supposed to be amongst themselves, but dealing with her has become an affair for the whole team, particularly Masami, when she accidentally messes up with her operations during the food festival. She is used to, and is excellent in, 1-on-1 basketball, but she was forced to play 5-on-5 during an important tournament, something she is not accustomed to, and against Keishin—the very team she crossed.
