Description
Anna Nishikinomiya is a main character and primary antagonist in her story. She is 17 years old and serves as the student council president at Tokioka Academy. She is the daughter of Matsukage and Sophia Nishikinomiya, two influential figures responsible for enforcing Japan's strict public morality laws. Due to being raised in this hyper-restrictive society by a mother who was extremely strict about eradicating anything lewd, Anna grew up profoundly naive about sexual matters. Her naivety is so pronounced that she cannot distinguish between what is appropriate and what is inappropriate, often failing to recognize overtly obscene materials.

At the beginning of the story, Anna is the perfect model of what the morality laws intend a citizen to be: a soft-spoken, kind, sweet, and innocent individual who is deeply devoted to maintaining moral purity. She is a strong and determined girl who loathes anything lewd and fights against it with all her power, which has made her popular and admired by the entire student body. Her strict, disciplined, and highly moral personality leads her to take her role as student council president extremely seriously, ensuring her school remains a place of absolute virtue.

Anna's entire worldview and personality undergo a drastic and extreme transformation after an accidental romantic encounter with Tanukichi Okuma, a boy she has known since childhood. This event awakens suppressed desires within her that she is completely unequipped to understand or control. Because of her extreme repression, she confuses the powerful feelings of lust for pure love, becoming convinced that only true love could make someone feel that good. This leads her to develop an obsessive, possessive, and unhinged infatuation with Tanukichi. While she becomes a sex-crazed individual who lusts after him, she paradoxically maintains her belief in her own purity and virtue, creating a bizarre disconnect between her actions and her perception of morality. Her behavior becomes increasingly erratic and aggressive, driven by jealousy and a desperate desire to claim Tanukichi as her own, often manifesting in violent and terrifying ways.

Anna’s primary motivation is to be with Tanukichi Okuma, whom she sees as the object of her pure love. Her role in the story begins as the righteous enforcer of moral law who commissions Tanukichi to help her hunt down the erotic terrorist Blue Snow. However, after her transformation, she becomes an unpredictable and dangerous figure whose actions, driven by her twisted understanding of love, often create chaos for the other characters. She develops an extreme jealousy whenever she sees Tanukichi with other girls, leading to confrontations where she has threatened others with weapons like scissors and a knife.

Anna shares several key relationships. Her primary relationship is with Tanukichi Okuma, her childhood friend and the target of her obsessive affection. She met him at a daycare when they were very young, and he was the first person to interact with her after a long period. She is also best friends with Ayame Kajou, who is secretly the erotic terrorist Blue Snow. Despite their friendship, Anna has physically attacked Ayame out of jealousy, stopping only because Ayame is her best friend. Her parents, Sophia and Matsukage Nishikinomiya, are the architects of the very moral laws that shaped her, with her father being a cold and practical politician who does not realize how his strict ideas affect his family.

Anna undergoes a significant and dramatic character development. She starts as the ideal pure maiden and the perfect product of the restrictive society. Her accidental kiss with Tanukichi opens a floodgate of repressed sexuality, causing her to devolve into a yandere—a person who is initially loving and sweet but becomes possessive and violent. Throughout the series, her obsession intensifies, leading to infamous acts such as giving Tanukichi cookies baked with what she called her love nectar and attempting to commit suicide after believing she had been aroused by another man. Near the conclusion of the story arc, after Tanukichi confesses his love for Ayame, Anna is rejected. Surprisingly, she accepts his feelings and returns to being a normal girl, showing a capacity for growth and acceptance.

Anna possesses several notable abilities. She has demonstrated superhuman strength, capable of breaking a doorknob apart from a door and breaking through a fence out of jealousy. She also gained a black belt in judo as a child and won piano competitions, showcasing a history of high achievement and physical prowess. Her most defining characteristic, however, is not a conventional ability but her extreme sexual naivety, which, when combined with her awakened desires, makes her both unpredictable and dangerously persistent.
