Yasutora Sado

About:
Sado, or usually called "Chad" is a very strong gentle teen who became friends with Ichigo before the start of high school. He is part of Ichigo's group because he once took care of a parakeet that had a soul inside it. Of course a hollow attacked, and Sado was actually able to fight it. Fortunately he was beat with Ichigo's help and the soul was sent to the soul society. Later Chad gains this new power which gives his right arm this black armour.

Appearance:
Sado is part Mexican, part Japanese, so his skin is naturally that color; no tan at all. His hair is dark as well, and it usually covers his eyes.

Style:
During his visit to the Soul Society, he wears a pair of jeans along with a blue shirt. Sometime during their stay, his shirt was ruined and Ishida ended up fixing it by added a stripe to his shirt.

Power:
At first one'd think that Chad's irregular strength and endurance for things was just something he was born with, and was nothing that would change. However, being handed a cursed (and caged) bird, he began detecting small traces of hollows. Of course, it was not until he fought off a hollow, with Karin Kurosaki, that he acquired his new found powers.

After realizing that his strength was to be used to protect people, he was able to find his own power; an armoured right arm. Known as "Brazo Derecha de Gigante", it became his defensive arm. With it, he could deliver powerful and heavy blows with one strike. Like Orihime, with training from Yorouichi, he managed to use his power at will and to deliver more constant blows.

Later on, Chad asks Uruha to train him. During his training, Chad had to go against Abarai's bankai form, while Uruhara took done some notes. After the extensive training session, Chad's right arm gained a new form. He also gained greater physical and spiritual strength than he had to begin with.

Furthermore, in Hueco Mundo, Chad had suffered quite a bit because he was unable to use his powers. However, after receiving a blow from a power that resembled his own, he was able to regain his spiritual power. With the powers back, and more to boot, he was able to stretch the power into his left arm! The left armoured arm becomes known as Brazo Izquierda del Diablo with its own attack, La Muerte, which released quite the damaging and deadly blow upon contact. After gaining the armoured left arm, he uses his right arm for defence while the left becomes the offence.

History:
He and Ichigo were attacked by the same gang, and had to save each other when they were in Junior High! Sado is a very strong guy who has extreme strength. He's half Mexican and half Japanese, his family has all past away like Orihime's, and he was left with his grandfather's necklace (Mexican coin on a chain).
