Ichigo Kurosaki (黒崎 一護, Kurosaki Ichigo) is a Human who has Shinigami powers. He is the son of Isshin and Masaki Kurosaki, and older brother of Karin and Yuzu. Ichigo looks like a normal teenage boy; the one exception to that is his spiky orange hair, a trait that he has been ridiculed about for years. He is a fairly tall, lean-built person with peach skin and brown eyes. 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 standard Shinigami attire with the addition of a strap across his chest. Initially, it was a thick brown belt to hold his Zanpakutō sheathe, but it later became a red rosary-like strap. The shape of them is a kite with a flat top and bottom. Ichigo's appearance has caused several people, including Jūshirō Ukitake, to notice a similarity to Kaien Shiba; the former lieutenant of the 13th Division.After training in the Dangai, Ichigo's hair grows considerably and is noticeably taller, as stated by his friends. However, after Ichigo loses all his spiritual powers, his appearance reverts to the way it was before his Dangai training.

Orihime Inoue (井上 織姫, Inoue Orihime) is a Human living in Karakura Town. She is a student at the Karakura High School, where she is in the same class as Ichigo Kurosaki and her best friend, Tatsuki Arisawa. Orihime is a teenager of average height. She has brown eyesand long, waist-length burnt orange hair. Her most noticeable physical trait is her slender yet curvaceous figure for a teenager, especially in terms of her large breasts. She wears her hair in bangs tucked behind her ears with hairpins, which she only removes to sleep, as they are worn in the memory of her brother. Orihime initially wears her hair with a full but parted fringe before pulling most of her bangs behind her ears as she was ready to leave for Soul Society, a change noted by Tatsuki.Seventeen months after Aizen's defeat, Orihime's hair becomes fuller and wavier. Her bangs naturally frame her face without her hair clips and also hang over her ears. She stops wearing hair clips and instead keeps them clipped onto the left collar of her school uniform.
