Movie
Description
Aoi is a student at Shin-Inaka no Chugakko, the rural junior high school that serves as the central setting of the story. He is a classmate of the energetic Wapiko and the level-headed Shuichi Kitada. Serving as the student body treasurer, he holds an official position within the school's leadership, which is headed by the once-wealthy heiress Chitose Fujinomiya. His physical appearance is distinctive and contributes to his mild-mannered delinquent image; he has blonde hair and is rarely seen without his sunglasses and a souvenir jacket.

Aoi is portrayed as calm and somewhat detached, often appearing unfazed by the chaotic events that regularly unfold around him. Despite his laid-back demeanor, he is noted for being one of the few individuals who can effectively manage and control both the impulsive Wapiko and the demanding Chitose, a skill that demonstrates his sharp perception and understanding of those around him. His motivation in daily life, however, is far less about school politics and more about his great love for bargain hunting. He is known to frequently skip school to take advantage of sales at the local supermarket, a hobby he pursues with a passion that borders on being his primary reason for living.

In the story, Aoi acts as a grounded presence among his friends. He shares a deep bond with Wapiko and Shuichi, having been their best friend since infancy. This long history gives him a unique ability to understand Wapiko's eccentric behavior, and he is often seen accepting her antics with a knowing tolerance. While Chitose frequently clashes with the other students, Aoi remains one of the few people she cannot easily push around, and their interactions are a source of comedic tension. The anime adaptation introduced romantic elements between Chitose and Aoi that were not present in the original manga, adding a layer of unspoken affection to their relationship. Conversely, he also attracts the unwanted attention of Chitose's rival, Yurika Sugadaira, who is infatuated with him.

Aoi's development is subtle, as he largely remains a steady, unchanging character amidst the more flamboyant personalities. His primary internal conflict seems to be his unwillingness to be drawn into the melodramatic schemes of the rich girls, whom he finds to be horrible people, and he often feigns ignorance of their advances. Despite his casual attitude and tendency to skip class, he is not truly rebellious; he fulfills his duties as treasurer and remains a loyal friend. His notable abilities include being athletically talented in most sports, a trait that contrasts sharply with his one significant weakness. Since drowning in a pool at the age of eight, he has been completely unable to swim. This vulnerability, paired with his reputation as something of a punching bag for Chitose, rounds out his character as more than just a cool and collected figure. His love for food is also a notable trait, as he can be easily lured or bribed with it, making his otherwise unflappable nature surprisingly easy to manipulate.
