Ayanojo Aburatsubo holds the vice-presidency of the Magic Users Club at Kitanohashi High School. This third-year student demonstrates notable skill in magic and athletic pursuits, juggling club activities with membership on the tennis team and in the drama club. His magenta hair and bishounen looks fuel his popularity, resulting in a dedicated female fan club at school.

Aburatsubo is homosexual, focusing his romantic attention exclusively on club president Takeo Takakura. He openly flirts with Takeo, adopting feminine mannerisms during these interactions. Takeo does not return his feelings, yet Aburatsubo persists despite recognizing the unlikelihood of success. This creates a dynamic where Takeo remains generally tolerant though often uncomfortable. Their interaction includes a moment in the television series where Aburatsubo steals a kiss from Takeo during the opening sequence.

His family life, explored in the television series, reveals a strained relationship with his overbearing mother. Her tendency to infantilize him causes him significant distress, especially during school events like parent-teacher meetings, though he retains underlying affection for her.

A subplot involves fellow club member Nanaka Nakatomi developing romantic feelings for Aburatsubo. After she confesses to him during the OVA series, he rejects her based on his existing attachment to Takeo. The television series later introduces ambiguity by hinting at potential reciprocity toward Nanaka, though this remains unresolved and unconfirmed.

Aburatsubo's character and primary motivations remain consistent across both OVA and television iterations. His role as vice-president and dedication to the club's activities persist throughout all official media, with no significant deviation from his core traits or relationships.
