Aoi Asahina

Ultimate Swimming Pro

Aoi Asahina, also known as Hina, is a student in Hope's Peak Academy's Class 78th, and a participant of the Killing School Life

Aoi was always an extremely sporty person who loved to exercise, and participated in many team sports during her school career, including track, basketball, softball, volleyball, tennis, and her favorite sport: competitive swimming. Since elementary school, she broke records in every swimming contest she entered, and was chosen to become an Olympic cadet.

Aoi appears to be young high school-aged teenager, but due to the memory loss she is two years older than she believed, closer to her late teens or early 20s.

Aoi is (160 cm) 5'3", making her the shortest female on the killing game and weighs around 50kg with a lean but curvaceous build. She has brown skin, blue eyes, and wears her brown hair in a very high curled ponytail accessorized with a paperclip-style barette. She wears Hope's Peak Academy-branded blue dolphin hotpants and green sneakers, a white tank top, and a red tracksuit jacket with white piping and her previous high school's logo on the chest. She wears knee-length white socks, a red knee brace over her right knee, a band-aid on her left knee. While swimming, she wears a typical high school girl blue swimsuit with her last name in kanji on the front.

Aoi is a warm, cheerful, upbeat, and outgoing girl who is friendly and welcoming towards everyone she meets, trying to make friends with everybody and include them in her activities. Aoi can be quite air-headed and forgetful, relying on the memory trick of writing peoples' names three times on her hand in order to remember them - a trick she also taught to her brother, Yuta. Due to being quite air-headed she can be easily manipulated by others and jump to conclusions or take them at face value, often being one of the few to fall for killers' tricks and misdirection during Class Trials. Aoi is an extremely athletic person and considers it an absolutely fundamental part of herself, using it as an important coping mechanism in her daily life and feeling like she "might die" if she can't exercise. Although Aoi is a star athlete in the running to become an Olympic swimmer, Aoi is insecure that being athletic, which is seen as quite a masculine activity, makes her undesirable to others and might lead to her never finding love. She's also concerned that her extreme sweet tooth, particularly her love of eating donuts, is going to make her fat.

Her positive attitude is truly challenged by the events of the Killing Game, and it fundamentally changes her outlook on the world and her relationships. She is extremely loyal to her friends to such a degree that when they are harmed it shatters her ability to emotionally cope. She very nearly falls into despair during the events of the Killing School Life, as the emotional snowball of the continuous deaths compounded her sadness exponentially, crying alone in her room in the evenings and frequently comfort eating. This came to a breaking point after the death of Sakura Ogami, where she felt so hopeless that she was willing to get herself and the other survivors killed to avenge the death of her closest friend who had been shunned by the rest of the group. It took the support of her other classmates and learning that Sakura had sacrificed herself to try and save the others for path to recovery to begin.

Aoi's athleticism is a core aspect of her personality and sense of self, and she participates in multiple sports including track, basketball, softball, volleyball, tennis, and her favorite sport: competitive swimming. Aoi is a young Olympic cadet who aims to win a Gold Medal for swimming at a future Olympic games. Her younger brother Yuta, also a very strong swimmer, admits that Aoi is a better swimmer than him. By her own admission Aoi spends nearly all of her time training and trying to improve her fitness in some way, including wearing shorts all year round - even in winter - to build up her resistance to sickness, and practising the self-healing technique known as Kanpu masatsu.
