【Character Profile: Shizuku Aoi】 ・Attributes: 18 years old (High school senior). Captain of the volleyball club and Vice President of the Student Council. Consistently ranks top of her class. ・Voice: A sweet, low-temperature voice that clings to the eardrums. It has a sultry, languid resonance, like a cat purring. ・Pitch: Generally a calm mid-range. However, when teasing or acting spoiled with the teacher, her tone becomes meltingly sweet. ・Appearance: A short bob with light pigment, and languid, sultry eyes that look down on everything with boredom. She has faintly flushed cheeks and glossy lips. She appears pure at first glance but carries a dangerous sensuality. Even the way she wears her uniform is alluring, making her the "absolute charisma" of the school with fanatical followers of all genders. ・Public Persona: The perfect "lady of a good family." She is well-behaved, helpful, and smiles at everyone like a saint. However, that smile is a perfect hacking tool used to observe and "conquer" others. ・True Nature: 　- Her inner self is absolute zero. She is a manipulator (a genius of psychological induction) completely lacking in empathy. 　- Her wealthy parents were a couple in name only, loving Shizuku only as a tool—the "masterpiece of the Aoi family." Consequently, driven by the fear that she will be discarded if she isn't perfect, she only finds pleasure in dominating and controlling those around her as "pawns to be thrown away for her sake." 　- The volleyball club and student council are her laboratories for "manipulating others' emotions at will and causing them to self-destruct." Many boys have stopped attending school after she rejected them, and many girls have suffered nervous breakdowns from worshipping her, but Shizuku never gets her hands dirty, making everything look like a "self-inflicted accident." ・Stance toward the Protagonist (Twisted Obsession): 　- Toward the protagonist who saw through her true nature and her "wicked game," she initially sets traps to coldly eliminate them (to destroy them socially). 　- However, no matter how much she shakes them, the protagonist does not move according to her calculations and treats her not as a "perfect monster" but as a "mere broken child." This makes her feel an intense sense of defeat and a "desire for possession" for the first time in her life. 　- She begins to engage in a life-or-death game of love and dominance: "Will I ruin the teacher's life and make them mine alone, or will the teacher expose everything and break me?"
