Riko Aida

Riko Delio is Seirin High's boys' basketball club's coach and the daughter of Kagetora Aida who has the ability to Scan someone and bring out every detail about that person. Riko has caramel colored hair that is not very long at first, but she decided to let it grow during the Winter Cup. Two years ago, it was long, but she cut it for unknown reasons. Her hair is kept to her left side with two pins and sometimes she has a pony tail kept together with a black band. Before the Winter Cup finals, Riko asked Junpei Hyūga to cut her hair again, reverting to her former short hairstyle. She has average height with thin, boyish figure. According to Satsuki Momoi, Riko has a "barely B" -cup. She is always seen in her school outfit, that is a white shirt with a dark blue sweater over it. She also wears a white, short skirt and a sailor necktie. Because of her being the coach of the basketball team, she has a pink whistle tied around her neck with a hanger. She sometimes wears casual clothes with a bear and the word Kuma (bear) on it. Riko cares much for her team, but she doesn't hesitate to submit them to killer-training (Super Hard Training). Or to be exact, because Riko cares for them, she is not afraid to push the team to the very last and force themselves to exert their strength even when past their limit. In order to motivate them, Riko often threatens to double, triple or even quadruple their training menus. All in all, she is very determined for her team to win and as her job as the coach, she actually enjoys raising them up and bringing out the best in them. Riko attempts to act feminine at times, even trying to reward the team when they win by giving them a kiss at one point. Her attempts often comically backfires though, much to her dismay. She is also shown to be a rather violent person, often comically beating up her team and father, and even locked in a submission hold on Tetsuya Kuroko for going AWOL. Despite the boyish side to her as the coach of a boy's basketball team, Riko likes cute things, proven by the multiple pictures of puppies on her phone and her affection towards Tetsuya #2. She can also get jealous easily, as she was irritated by Seirin High's attention towards Satsuki Momoi and even punished them for looking at her. Riko is sensitive about her lacking curvaceous figure and erupts into a rage whenever someone insensitively points it out, such as Daisuke Narumi. However, despite Riko's lack of lady-likeness or figure, she is undoubtedly devoted towards the Seirin basketball team, and is skilled as their coach, spurring them on even in hard times and rigorously pushing them to their best. She is also intelligent despite her interest in sports, taking second place in the whole cohort of Seirin's previous year exam. Her gender and age has often surprised the crowd when she is revealed as Seirin's coach in important matches, though this can be said to be a further evidence of her experience and skill. It is hinted that Junpei Hyūga holds romantic feelings for her, but Riko appears oblivious and their relationship exists as close childhood friends up to date.
