Ichigo's most distinguishing feature is his spiky orange hair, a trait he has been ridiculed about for years on end. He is a fairly tall, lean-built seventeen year old with peach skin and brown eyes. He likes to wear slim fitting clothes. He has a tendency to wear shirts patterned with the number 15 because his name is a homonym for the number. Since becoming a Shinigami, he has become noticeably more muscular, as noted by his sister Karin. When in his spiritual form, Ichigo wears the standard Shinigami shihakushō, with the addition of a strap across his chest. Initially, it was a thick brown belt to hold his Zanpakutō sheath, but it later became a red rosary-like strap after awakening his own Shinigami powers. It is shaped like a kite with a flat top and bottom. Ichigo's appearance has caused several people, including Jūshirō Ukitake, to note a similarity to Kaien Shiba, the former lieutenant of the 13th Division. After training in the Dangai, Ichigo's hair grows considerably, and he is noticeably taller, as stated by his friends. After Ichigo loses his Shinigami powers, his appearance reverts to the way it was before his Dangai training. As a teenager, Ichigo is stubborn, short-tempered, strong-willed, and impulsive. Despite claiming not to care about what other people think about him, he attempts to maintain a detached and "cool" image. He generally keeps his face set in a near-permanent scowl, with his eyebrows drawn together. His outspoken, hot-headed demeanor is a trait Ichigo himself has acknowledged, and if somebody picks a fight with him, he cannot help fighting back.
