Chad is a teenager of Mexican descent. He is extremely tall and appears to be much older than he actually is. Chad has a tattoo on his left shoulder which reads Amore e Morte ("love and death" in Italian) and consists of a heart, a snake and angel wings around the heart. In the series, he is usually seen wearing either his school uniform or a tee shirt. At one point in the series, he is seen wearing a dark, long-sleeved shirt with a rose emblazoned on the left sleeve. The rose may be in honor of his grandfather seeing as how his grandfather's name was Oscar Joaquín de la Rosa, de la Rosa being Spanish for "of the Rose." His first name can mean "Calm Tiger" when broken up into Yasu(calm) and Tora (tiger).
