Aoi Ogata is a junior secretary of

Aoi Ogata is a junior secretary of President Takishima, Kei's grandfather, and often serves as the President's emissary. A young man of exemplary ability, 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. He first appears in chapter 27.
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. His various attempts, including threats and bribery, all fail due to Kei's interference and Hikari's own stubborn nature. Though Aoi does not relent his attempts to persuade Kei to move to London, he comes to respect Hikari as someone who makes Kei happy and sincerely likes her. After Hikari learns how much Aoi admires Kei, she and Aoi form the "After School Takishima Fan Club," in which Aoi is the president while Hikari's job is to primarily send photos she takes of Kei to Aoi. Aoi eventually 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.
