Iori Yukidou is a 16-year-old with spiky blond bangs and waist-length hair, blue eyes, and pale skin. Her feminine presentation coexists with both male and female reproductive organs, classifying her as a futanari. This results in an unusually large and easily aroused male anatomy, creating significant personal and social challenges.

As the younger sister in a wealthy family, she faces constant comparisons to her accomplished older sibling, Kaori. Her parents express disappointment at her birth, having desired a male heir. This dynamic fuels her feelings of inadequacy and isolation.

Her physiology triggers uncontrollable urges, compelling frequent self-gratification in risky public spaces like restrooms or streets. This habit often delays her school arrivals. Despite these compulsions, she clings to a conservative stance on virginity, intending to preserve it until marriage—creating tension between her actions and values.

Under the alias "Alice Akanemi," she adopts an online persona as a "Chinpo Idol" (Penis Idol). Wearing a modified maid outfit, she hosts webcam sessions where fans direct her activities. This alter ego channels fantasies of sexual interactions with Alice or self-impregnation, starkly contrasting her real-world aspiration for conventional heterosexual marriage.

Outwardly shy yet internally exhibitionistic, she embodies a "closet pervert" archetype. Emotionally volatile, she often refers to herself in the third person. Her struggles involve juggling societal norms, family pressures, and secrecy about her biology. Takahashi, the family butler, monitors her safety due to unpredictable routines tied to managing her urges.
