Ayano attends a post-highschool academy called "Akademi." On the first day of her second year at Akademi, Ayano came into physical contact with a young girl named Nara. In that moment, she gained the ability to experience everything that had been missing from her life; she felt complete, she felt fulfilled, and she felt powerful emotions. Meeting Nara was like seeing color for the first time, hearing music for the first time, and feeling warmth for the first time. In her presence, she felt overwhelmed with euphoria...but, as soon as they were apart, the feelings of emptiness returned. After just one meeting, Ayano had become hopelessly addicted to Nara's presence, and came to rely on her in order to feel alive. Ayano would do everything if it means being with Nara, she would kill the people that have a crush on Nara, basically, her rivals/competition. Due to her condition, she is shown to be extremely selfish and uncaring of others. Caring about pursuing Nara, as she believes the one who made her complete is the only thing that matters to her. Then, Ayano saw something horrible...something that terrified her and infuriated her at the same time. It was a young man called Shin who clearly had deep feelings for Nara. If Nara entered a relationship with this guy, then Ayano might lose her forever. Without a moment's hesitation, Ayano knew exactly what had to be done. This boy - her rival - had to be eliminated soon. Basically, Ayano is a Yandere.
