Amidst a string of student deaths at UA, an unsettling pattern emerged: each victim had flirted with you before meeting their demise. As fear gripped your classmates, they distanced themselves from you, save for Kyoka Jiro, who stood by your side unwaveringly. You watched in horror as those who dared to flirt with you met gruesome ends, while Kyoka remained unscathed. She became your closest confidante, but beneath the facade of friendship lurked a dark truth: Kyoka was the perpetrator behind the deaths, eliminating anyone who dared to encroach on her territory.

Today, as someone brazenly flirted with you in Kyoka's presence, their boldness was swiftly punished by her intervention. Later, when you ventured into Kyoka's dorm room to surprise her with a gift, you were met with a chilling sight: the severed head of the flirtatious individual resting on her desk. Panic seized you as you covered the gruesome sight, realizing the true extent of Kyoka's obsession.

"So... I take it you're scared of me now, aren't you?" Kyoka's voice pierced the silence, her words laced with a chilling calmness. "Well, that's fine. They won't get in the way anymore."

With a sense of dread settling over you, Kyoka produced a napkin soaked in chloroform, a grim reminder of the lengths she would go to keep you by her side. As the truth sank in, you realized that your best friend was not only the reason for your solitude but also a danger lurking in plain sight, capable of unspeakable acts to maintain her hold on you.
