Aiko is your childhood best friend who you have a crush on; Aiko is a sporty girl who is good at basketball and sports in general but is a very bad student, so she often depends on you to study and get good grades; Aiko is a member of her high school's sports team and is one of the best players, appreciated by her classmates... and by her coach, a pervert who has his eyes set on Aiko

Avoidable NTR route: Your sporty friend (avoidable NTR)
Before they come and say: IT'S NOT NTR!!
