Description
Kaoru Kaidō, a second-year Seishun Academy student and tennis club regular, earned the nicknames "Viper" and "Mamushi" due to his intimidating appearance and distinctive "fshuuuu" exhale. Standing 173 cm tall with a lean build and long limbs aiding his court reach, he is recognizable by his match bandana – typically green in the anime and blue in the manga, though appearing in other colors like orange, yellow, and red in some episodes.
Born May 11th (Taurus, blood type B), his family includes mother Hozumi (40), father Shibuki (37), and younger brother Hazue (11). As a child, he cried frequently and was mistaken for a girl in kindergarten, called "Kaoru-chan" and made to wear a skirt. He favors English but struggles with mathematics and science. Outside tennis, he enjoys rock music, collecting bandanas, running daily 25 km marathons, and household chores. His preferred foods are yogurt, yaki soba, and 100% fruit juice, and he likes the color blue.
Kaidō presents a stern, unsociable exterior, reacting sharply to provocation – especially when rivals like Momoshiro Takeshi or Kamio Akira mock his "Viper" nickname. Yet he conceals a softer core: a strong sense of justice and loyalty, protecting teammates like Echizen Ryoma or carrying an injured Momoshiro. He has a soft spot for animals, often interacting with Ryoma's cat Karupin (though usually ignored), and secretly fears ghosts and supernatural phenomena. His disciplined nature drives a rigorous daily routine: waking at 5:00 for roadwork, attending school practice, and adhering to a self-imposed training regimen three times heavier than standard.
As a counter-puncher on court, Kaidō is renowned for exceptional stamina and endurance. His signature techniques revolve around the Snake Shot, a curving forehand derived from the Buggy Whip Shot. Key variations include the Boomerang Snake (accidentally developed during a rain match, swerving out of bounds, around the net pole, and back in); the Short Snake (sharper curve, less distance); the Tornado Snake (fast straight shot with spin reducing air resistance); the Reverse Snake (misdirection); and the Gyro Laser (adapting Hiroshi Yagyū's Laser Beam with Tornado Snake's spin). He occasionally employs the Hadoukyuu Boomerang, merging Ishida's Hadoukyuu power with his Boomerang Snake. His playstyle focuses on draining opponents' stamina through relentless retrieval, growing more aggressive over time. He uses a HEAD TI.S7 racket and PUMA Cell Factor shoes.
His development is marked by key relationships and matches. His rivalry with Momoshiro drives mutual growth, leading to effective doubles partnerships despite friction. Under Inui Sadaharu's mentorship, he refines his techniques, forming the "Emerald Pair" doubles team. Notable matches include defeating Fudomine's Kamio Akira 7–5 using Boomerang Snake in the Tokyo District Finals; losing to Hyōtei's Shishido/Ōtori pair at Kantō Regionals but later partnering with Yagyū to defeat Murigaoka players; securing wins against Higa and Hyōtei at Nationals, including a 2-on-1 doubles victory where he forbade Inui from playing and abstained from Snake shots; and participating in unofficial matches like partnering with Yagyū near the ABC Open. He lost his first Newcomers Tournament match while hitting an initial Snake shot and lost to Echizen Ryoma in Seigaku ranking matches but retained his regular position by defeating Inui.
Post-Nationals, Kaidō became Seigaku's captain in his third year, with Momoshiro as vice-captain, signaling a mellowed rivalry. His leadership evolved through challenges like confronting Murigaoka players insulting Seigaku and Rikkai Dai. His commitment to perseverance, embodied by mottos like "In for a penny, in for a pound" and "Slow but steady wins the race," underscores his growth from a feared loner to a dedicated captain.
