Iku Sutou

Iku loves baseball, to the point of spending hours recruiting for her team when it's on the verge of being disbanded. She is determined to do her best no matter what; because of this she's described as the embodiment of "stoicism" by Rentarou. Iku is also wildly masochistic, going so far as to train for hours until her body is in agony so she can enjoy the pain.
