Yasutora Sado (茶渡 泰虎, Sado Yasutora), also known as Chad (チャド, Chado), is a Human teenager who lives in Karakura Town. He is a student at Karakura High School, where he is in the same class as Ichigo Kurosaki.
Sado is a teenager of Mexican descent with wavy brown hair that generally hangs over his brown eyes. He is a muscular and extremely tall man and appears to be much older than he actually is. Sado has a tattoo on his left shoulder which reads Amore e Morte ("love and death" in Italian) and consists of a heart with a snake and angel wings around it. He typically wears either his school uniform or flashy short-sleeved shirts with open collars. He also wears a dark, long-sleeved shirt with a rose emblazoned on the left sleeve. Seventeen months after Aizen's defeat, Sado has grown a small goatee on his chin.
Sado is a quiet person and is sometimes the subject of jokes or bullies because he never fights back. Nonetheless, he is treated equally within his group of friends in Karakura. Sado also has a soft spot for cute things, like small animals and Kon's plushie form. Sado has also shown to be very intelligent; he ranked 11th out of 322 students in Karakura High School. Sado has a very loyal personality. He is quite loyal to his friends, especially Ichigo, who is one of his closest friends, even going as far as to try and defeat a Gotei 13 captain to go help him. He is also shown to be fearless and told so by numerous enemies such as the first Hollow he fights. He displays little emotion except when something he cares about is in danger.
Sado's favorite food is tomatoes. He also likes music, but rarely watches TV. He only likes two shows, one of which is Carnivore Kingdom, which starts at 8 a.m. on Sundays. He likes it so much that he bought the DVDs for it. As Kon is a cheap knock-off plushie of the main character of Carnivore Kingdom, Sado finds Kon especially cute. The other show he likes is Don Kanonji's Ghost Bust. Sado also has a bass guitar.
