Biography

Prior to the events of the main story

Upon entering Seigaku as a first year student, he was able to talk to Momoshiro Takeshi for the first time, which later became his rival in Seigaku's tennis club.

He also participated in the Newcomers Tournament against an unnamed opponent. Although he lost the match, he was able to hit his first Snake shot.

School Ranking Tournament

As one of Seigaku's regular members, Kaidou is the first serious opponent Echizen Ryoma faces during the Seigaku's Ranking Tournament. Kachiro Kato reveals a recording of one of Kaidou's prior matches, showing his extreme play that causes the other first years, Horio Satoshi and Mizuno Katsuo, to fear for Echizen's next match. Despite the concerns of his peers, Echizen remains unaffected and proceeds to the match against Kaidou. Early on, the match advances in favor of Kaidou due to his strategy to drain Echizen's stamina through his Snake shot, which forces Echizen to repeatedly run to both ends of the court. However, as the match continues, Kaidou is shown to become increasingly exhausted while hitting Echizen's returns that seemingly became stronger and faster to him. It is revealed by Inui Sadaharu that Echizen had aimed his returns at Kaidou's feet, resulting in Kaidou being forced to bend low and return the shot and using 2-3 times the normal strength and causing him to lose more stamina. In the end, Kaidou fell for Echizen's strategy and loses the match 6-4.

Trivia

• Once, as a primary school student, he was forced to wear a skirt and cried. This fact was also brought up by Konjiki Koharu during Nationals.
• According to Konomi, Kaidou was named "Kaoru" in order to highlight the gap from having a cute name with a stern face.
• Kaidou's signature snake shot was inspired from Konomi's upperclassman, who once put a spin on a ball. This prompted him to include a similar move in the story. Additionally, as the first opponent in the story who makes Echizen Ryoma serious, he wanted to show the intensity of tennis by omitting all words when drawing the match scenes between them during the School Ranking Tournament.
• When asked what part of the character design he is fixated on, Konomi said he focuses most on the line for Kaidou's lips and the eyelashes under his eyes. He wanted to make his eyes glaring so he would have a hungry look.
• After drawing for so long, Konomi stated that he has shown Kaidou's good points, such as his love for animals and his courtesy. Over the course of New Prince of Tennis, he wants to show the same hungriness he showed during the match with Tezuka Kunimitsu in a new light.
• Konomi stated that if he switched places with Kaidou for a day, there wouldn't be any benefits except for trying out training and running 42.195km (Kaidou's record in primary school).
