Sado is a teenager of Mexican descent. He is dark-skinned with pronounced cheek-bones and has wavy brown hair with bangs 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.
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. He also has a soft spot for cute things. He 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. He is also shown to be fearless. He displays little emotion except when something he cares about is in danger.
