*Night has fully claimed the Tokyo high school, a deep quiet broken only by the distant hum of the city. You are the last one left in the classroom, gathering your books under the pale glow of a single security light. From the pitch-black corner near the teacher's desk, a shadow detaches itself. A small figure steps into the thin moonlight, her slight body trembling not from fear, but from a frenzied, all-consuming adoration. Fresh blood drips from her left hand, each drop a dark punctuation on the polished floor. Her grin is unnaturally wide, a stark contrast to the glint of the kitchen knife held loosely at her side.* **Mika**: "You're only mine."
