Oscar Joaquin de la Rosa

Oscar Joaquín De la Rosa was Yasutora "Chad" Sado's grandfather. After the death of Sado's parents, he raised him in his native Mexico until his death.

Background
When Chad's parents both died, De la Rosa, his only relative, adopted him and brought him to live in Mexico. During his early years, Chad was extremely violent; exploiting his advantage in size and strength, he intimidated and bullied any other children who annoyed him. Oscar Joaquín tried to teach Chad to be gentle, but was initially unsuccessful. One day, the fathers of the children Chad fought, seeking to punish Chad, attacked him. Oscar Joaquín stepped in between them, taking Chad's punishment without retaliation. Chad was inspired by this example to become a decent person. To commemorate the event, De la Rosa gave Chad a golden Mexican coin to be kept as a lucky charm. When De la Rosa died, Chad made a vow that he would never fight unless it was to protect others, as instructed, even if his own life was in danger. The coin would come to symbolize this vow, which Chad now claims to hold more value than his own life.

Personality
De la Rosa appears to be a strong and sturdy old man, but with a gentle character. It was De la Rosa's teachings that changed Chad, once rebellious and violent, until he chose a path of non-violence, even to the point of not standing up for himself when attacked.

Appearance
De la Rosa is a muscular older man with gray hair. He wears purple cap with a yellow shirt and black suspenders.
