Aki Yazaki

Aki Yazaki (矢崎 亜紀 Yazaki Aki) is one of the characters in the light novel High☆Speed! written by Kōji Ōji and was one of Haruka, Makoto, and Rin's classmates from elementary school. She was also in the same swim club, Iwatobi Swimming Club, as Haruka, Makoto, Rin, and Nagisa.

Appearance
Aki's appearance is never mentioned in light novel. However she is mentioned to always be wearing a white muffler that is later stained brown after it falls into a river.

Personality
Aki is a kind and sweet girl who always seems to have a "sunflower" smile. Because of her cheery disposition she always sees the silver lining in any situation.

She is also someone who values the relationships she has such as wanting Haru to depend on people and make friends, referring to her relay team as her sisters, and crying at her and the boy's elementary graduation ceremony.

Even in stressful situations she can keep a clear head and take charge such as when Haru almost drowned in the river, she was able to call the ambulance, swim club, and Haru's mother while Rin and Makoto saved him and didn't cry even though she looked like she was going to.

History
In the same competition where the boys won first place in their relay, Aki and her friends won bronze in the girls relay.

Trivia
Despite what the anime shows, Aki was actually the one who came up with the sentence 'I swim best free for the team' on the school bricks
