Isshin Kurosaki, formerly known as Isshin Shiba , is the former captain of the 10th Division, husband of Masaki Kurosaki, father of Ichigo Kurosaki, Karin Kurosaki, and Yuzu Kurosaki. Isshin is the former head of a branch of the Shiba Clan and the current head of the Kurosaki Family.
Isshin is a tall, muscular man with spiky black hair and brown eyes. He has thin facial hair around his mouth and on his cheeks. As a doctor, Isshin usually wears a white lab coat over his otherwise more casual shirt and trousers. He has the appearance of a man in forties, as noted by his daughter, Karin.
As a Shinigami, he wears the standard Shinigami Shihakushō, along with a tattered captain’s haori, worn like a sash and fastened over his left shoulder with the Division insignia obscured.
