Karin Kurosaki

is the cynical and sarcastic daughter of Isshin Kurosaki. Compared to her soft-spoken twin-sister, Yuzu, Karin is the more authoritative of the two. She is an excellent soccer player with a kick powerful enough to hurt weak Hollows. 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.

Karin is a sensible person and will not hesitate to kick her father in the head when she thinks he's acting unreasonable. She initially claims that she believes spirits do not exist, but she can see them just as well as her brother Ichigo can. She can also sense them from great distances, which usually manifests as a headache. In spite of her attitude about spirits, Karin is willing to use her abilities to earn a little cash, such as her position as Karakura Red of Don Kanonji's Karakura Superheroes.

In the beginning she got sick when connecting with Chad's bird, which had the soul of a young boy inside it. She was the first to realize that the bird was a boy who was dead and was being used by a Hollow to help it murder people. Ichigo says that it was the first time he had seen her cry since their mother had died.

Karin actually knows that Ichigo is a Shinigami and, of concern, wants to know why he's suffering. In the anime she also met Tōshirō Hitsugaya when he helped her at a soccer match and revealed himself as a shinigami. Karin is a homonym for Japanese quince, a name of a fruit, which matches Ichigo's name being a homonym for strawberry and Yuzu's name being a homonym for citron.

Powers and abilities
Strength:

Spiritual Power: Not much is known about Karin, but she is able to at least see spirits like her brother Ichigo can (prior to him obtaining shinigami powers). Tōshirō Hitsugaya also mentions, in the anime, that Karin has very high spiritual power, as she is able to see him.

Strong Kick: As demonstrated in the anime, her kicks were strong enough to hurt weak hollows.

Keen Aim: Karin is also talented at soccer which would strengthen her physical power. Her way of defeating rather weak Hollows is that she kicks a soccer ball at them. So far, as seen in the anime, whenever she kicks a ball at a hallow it always hits the Hollow's mask.
