Although she appears like a very feminine, girlish person, Karin is in actuality the quarterback for the Alexanders. First seen around the showy fourth-stringer Ibarada, Yamato is forced to defend her whenever she isn't on the field. Karin is revealed to be the first string quarterback for the Alexanders. She has Sena's immensely shy personality, which everyone noticed right away. Hiruma told the team that Karin was actually a man so that they would go all out on her (although Sena and Monta knew that she was a girl already). She has many male fans in the audience because of her beauty, including those from Shinryuji.
Karin was first recruited on the team after being scouted by Taka. One day, Karin was passing the football field, when Ibarada mis-threw a pass, and it hit Karin's bag. Asking who she should throw it back to, Taka raised his hand. She sent the ball spiraling beautifully, with perfect accuracy, back to him. Taka immediately told Heracles and Yamato to make her join the team, even admitting that she had "pure talent." Karin had at first rejected, due to her modesty and insecurity, but then when Yamato started to talk, Karin found it difficult to argue with him. She joined the team, and though the training was hard, like Sena, she grew to love American Football, and stayed with it. She also enjoys drawing and playing the piano (which is where she got her skillful fingertips, as pointed out by Heracles).
