Ayanojyo Aburatsubo is a third-year student at Kitanohashi High School and serves as the vice president of the school's Magic Club. He comes from an affluent family, and his surname contains characters that can be interpreted as "oil pot," while his given name blends characters meaning "design," "this," and "help". This character is visually striking, with shoulder-length pink hair and green eyes, often accessorizing his school uniform with items like hats and earrings.

Personality-wise, Ayanojyo is a complex figure who presents different sides of himself depending on the situation. With most people, especially his many admirers, he adopts a composed, princely, and charismatic demeanor that has earned him significant popularity and a dedicated fan club of female students. However, in his interactions with the club president, Takeo Takakura, his behavior shifts dramatically to a more flamboyant and overtly camp manner, characterized by persistent and playful flirtation. Despite this outgoing and confident exterior, he has moments of introspection and vulnerability, particularly regarding his family and his unrequited feelings.

A central aspect of Ayanojyo's character is his unreciprocated romantic love for Takeo Takakura. He is openly homosexual, but his affections are exclusively fixed on Takeo, and he shows no romantic interest in any other male characters. He understands that Takeo is uncomfortable with his advances and will never return his feelings, yet he continues to flirt, seek physical closeness, and even steal a kiss from him, accepting the lack of reciprocity. His role in the story is heavily defined by this pursuit, but he also plays a key strategic role as a powerful and reliable magic user within the club, forming a cornerstone of its success alongside the president.

His family background reveals a strained relationship with his overbearing and excessively doting mother, Akiko. She behaves in an infantilizing manner, especially during school visits, which causes him significant embarrassment and anxiety. This familial tension fuels his disdain for appearing vulnerable and contributes to his drive to maintain control over his public image, contrasting sharply with his usual social confidence. Despite the embarrassment, he is confirmed to have underlying affection for her.

Ayanojyo's narrative arc involves a gradual shift from a purely one-sided infatuation toward more nuanced emotional growth. He becomes the object of affection for fellow club member Nanaka Nakatomi, who has her own unrequited feelings. When she confesses to him, he gently but firmly rejects her, explicitly citing his preexisting love for Takeo as the reason. Towards the conclusion of the television series, some ambiguity is introduced regarding his dynamic with Nanaka, hinting at a fragile mutual understanding or a potential, though unconfirmed, future connection, which underscores the complexity of his relational navigation.

Beyond magic, Ayanojyo is a multitalented individual who excels in academics and athletics, actively participating in other clubs such as the tennis team and the drama club. This wide range of skills contributes to his status as a school idol and "The Ace," though he privately acknowledges that his ease with various pursuits sometimes diminishes his enjoyment due to a lack of challenge. In combat, he is known for his exceptional magical prowess, rivaling that of Takeo Takakura. He prefers to use offensive magic strategically, relying on sharp analysis and adaptability rather than raw power, which makes him a reliable and potent asset to the Magic Club.
