Yasutora Sado

Yasutora Sado is a teenager who studies in the same class as Ichigo Kurosaki. Because Ichigo first read Yasutora's name off a nametag, he pronounced his family name as Chad.

Personality
Chad is a tall teenager of Mexican descent, and appears to be older than he really is. He has a tattoo on his left shoulder that consists of a winged heart and a snake, with a ribbon that reads 'Amore e Morte' ("love and death" in Italian). During his early years, Chad was extremely violent. Exploiting his advantage in size, he intimidated and hit any child who annoyed him.

Oscar Joaquin, his grandfather inspired Chad to be gentle. Afterwards, Oscar Joaquin gave Chad an old Mexican coin, which he treasured after Oscar's death.

Chad is a quiet person and is sometimes the subject of jokes or bullies because he never fights back, against ordinary humans, or often hollows and Soul Reapers until necessary. Nonetheless, he is treated equally within his group of friends in Karakura (Ichigo, Keigo and Mizuiro). As he and Ichigo have a longtime relationship, having met each other while fighting off a group bullies. Since then both decided to fight together, Chad becomes determined to make several trainings to aid Ichigo in his fights as Ichigo and his enemies start becoming much stronger than Chad along the series.

Abilities
When first introduced, Chad had no special powers aside from his unusual strength and endurance. After his encounter with the cockatiel containing the soul of Yūichi Shibata, he starts to detect the approximate locations of spirits and hollows, but cannot fully see them.

Only after saving Karin Kurosaki from a hollow, during the hollow-slaying match between Uryū and Ichigo, did Chad begin to fully see spirits.After training with Renji, Chad gains an improved version of his armored arm. He also gains a new special attack called El Directo.

Chad's armored left arm, used for attack, is known as the Brazo Izquierda del Diablo.With this arm, Chad gains a special attack known as La Muerte,
