Cavi Campbell

thumb|Cavi loses his composure when faced with failure Cavi is a highly ambitious and competitive individual who appears to thrive on control and influence. He comes across as proud and authoritative, often asserting his dominance through events such as the underground Campbelldon tennis tournament. Cavi expects success from those around him, especially his children, whom he openly pressures during competitions while expressing strong confidence in their abilities. However, when faced with the prospect of failure, he can become visibly frantic and quick-tempered, as demonstrated when he desperately urged his children to win after they began losing their advantage in the tournament finals. He is willing to employ underhanded methods to secure victory, overseeing a tournament where sabotage, performance-enhancing drugs, and other illicit tactics are permitted. Despite this, he occasionally shows a softer side, such as when he becomes emotional while watching his son's growth following the finals.

Cavi is an older man of average height. He has sharp, drooping eyes and small brown eyes. Cavi's hair is medium-length gray, with a thick strand hanging on the right side of his face. He also has a thick moustache and a soul patch under his lip. Cavi wears a black suit with a black and white patterned shirt and a navy blue tie. In the anime, the shirt is maroon and the tie is white. He also wears semi-rimless glasses.
