Aoi Ogata is a junior secretary of President Takishima, Kei's grandfather, and often serves as the President's emissary. He is nineteen years old. Aoi has a cold and calm character, and has always been expressionless, not smiling even once, but is actually kindhearted and socially awkward in some respects. Like Kei, he has the ability to see something only once and memorize it, though his ability made him a victim of teasing as a child. He first met Kei when he was eight and Kei was five, and came to admire and deeply respect Kei, coming to see him as an almost kindred spirit. Aoi initially appears when he is sent to Japan from London, on orders to convince Kei to transfer to London, which had been planned by Kei's grandfather. When Aoi discovers what is causing Kei to hesitate, Aoi tries to eliminate the problem: Hikari. He tries to threaten her, and Kei tries to beat Aoi up for threatening Hikari, but fails; even though he knows he is not going to convince Kei. Aoi then tries to bribe her but ends up having a cheque ripped to pieces by Hikari. At sometime, Hikari confronts Aoi and they both make up the "After School Takishima Fan Club," in which Aoi is the president and Hikari gets pictures of and writes up reports about Kei and sends them to Aoi. Afterwards, he realizes that he should not pressure Kei into the situation that he is not ready for and also realizes that he is most at peace when he sees Hikari and Kei smiling. He first appears in chapter 28.

Hikari Hanazono has always been second to Kei Takishima. When they were six years old, their pro-wrestling loving fathers introduced them to each other. Assuming that she was the best in wrestling, young Hikari challenged Kei to a wrestling match only to be thoroughly defeated by him. 
Ever since that fateful incident, Hikari swore to beat Kei in school grades, sporting events - anything. To do this, she has enrolled in the same school as Kei since elementary. Now she attends Hakusenkan, an ultra elite school, that costs her carpenter father a lot of money. 
Hikari and Kei are the top two students in the school, with Kei holding firmly to that number one position. While Hikari considers Kei to be a rival and important friend, she is completely unaware that Kei loves her. The story primarily focuses on Hikari and her constant attempts to defeat her one and only rival, Kei, and how she finds love in their rivalry.
