Billy Cassidy
ビリー・キャシディ
Billy grew up on a ranch in an unknown city in the American West. His family moved to Los Angeles when he was 12 and he was never able to adapt well to “city life.” He began to play tennis to become a person worthy of attention to the girl he fell in love with at first sight, Stephanie. His skills include the bull rope serve, which seems to have been adapted from the cowboys in the American west.
