Karin Kurosaki

Karin Kurosaki (黒崎 夏梨, Kurosaki Karin) is the fraternal twin of Yuzu. She is typically cynical and sarcastic, and is significantly more assertive and aggressive than Yuzu. Karin is a no-nonsense kind of person and so does not hesitate to kick her father in the head when she thinks he is acting unreasonable. Karin's tough exterior results from her mother's death; because she could not be useful around the house like Yuzu, she resolved never to cry so that she would not burden her family with her personal troubles. Like Ichigo, Karin is spiritually aware, though she initially chooses to ignore the spirits she sees. Once Ichigo becomes a Soul Reaper and starts combating hollows on a regular basis, she takes a greater interest in the spiritual world out of concern for him. When dealing with hollows herself (typically in omake chapters) she uses her prodigious soccer talents to deliver powerful blows to weak hollows. She is aware of Ichigo's Soul Reaper powers, and tells him of this, but Ichigo decides to act as if he does not know what she is talking about.Rie Kugimiya voices her in the Japanese series and Kate Higgins in the English adaptation.
