Kaoru KAIDOU

Kaidou is a second year regular of the Seigaku tennis club. He has a very harsh appearance that is often very frightening to those around him, but despite his scary face and sharp demeanour, Kaidou harbours a particular fondness for cats. Kaidou has a habit of exhaling in a way that makes him sound like a snake, which has earned him the nickname of ‘Viper’. He gets on very well with Inui, who helps him to develop his skills, but he seems to particularly dislike Momo, whom he sees as his rival.
