Description
Aria Shichijō holds the position of student council secretary at Ōsai Academy. Initially a second-year student, she progresses to her third year. Her background stems from the affluent Shichijō zaibatsu family, whose lavish pampering cultivates pronounced airheaded tendencies. These manifest as frequent misinterpretations of mundane scenarios—expecting standard doors to slide open automatically or stationary staircases to function like escalators.

Physically, she exhibits pale skin, light brown hair extending down her back with bangs obscuring the right side of her face, and light brown eyes. Recognized among the academy's most alluring students, her mature, buxom figure accentuates Shino Amakusa's chest-related insecurities. She stands 1.68 meters tall and weighs 59 kilograms.

Despite her privilege, Aria displays generosity by leveraging family resources to fund student council activities and group excursions—ranging from hotel stays and cultural events to club outings like those of the judo club. Academically proficient, she ranks second in her year's midterms, trailing only Shino.

Her personality merges a calm, motherly disposition with intense perversion. She routinely employs sexual innuendo and exhibits pronounced interests in bondage (as both dominant and submissive), enemas, and exhibitionism—traits exceeding even Shino's and partially rooted in early childhood exposure to inappropriate materials. Aria openly jokes about anal sex and discusses lower-body anatomy. Notably, she typically forgoes underwear at school in favor of a chastity belt, relying on her maid, Sayaka Dejima, for hygiene management.

Shino Amakusa stands as her closest and longest-tenured friend. Their interactions amplify each other's perverse remarks, though Aria's extremes often compel Shino to adopt a straight-woman role. Her dynamic with Takatoshi Tsuda shifts notably: initially deemed less intimidating than other council members, his caution grows upon recognizing her perverse nature. A pivotal moment arises in chapters 277-278 when Takatoshi selects her as his play partner, delivering a romantic speech that triggers her blushing and ignites genuine romantic feelings. This spurs proactive behavior, such as exploiting his temporary butler role to stay near him or perching on his legs during story readings. By chapter 344, his presence causes heightened heartbeats and insomnia; in chapter 542, she sleeps using his arm as a pillow, admitting comfort. Her maid, Sayaka Dejima, shares similar perverse inclinations, and their relationship thrives on mutual support, with Aria deliberately provoking Dejima's moods.

Aria's development reveals subtle vulnerability tied to romantic feelings, contrasting her usual composure. The origins of her twisted tendencies are partly attributed to parental influence, including the circumstances of her conception during outdoor sex.
