Aoi is the junior secretary of President Takishima. He is nineteen years old, 3 years older than Kei, but he has the same ability, remembering something he sees once forever.
Aoi always appears in a black suit, complementing his black hair and black eyes. He always seems very casual and shows no emotion.
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 a school in 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, Kei tries to beat Aoi up, but fails; even though he knows he is not going to convince Kei. He 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 27. He and Alisa Appleton also start to develop feelings for each other. In SA Jougai Rantou, they are married.
