Their latest clients are Yumasaki and Karisawa, who want them to find the costumed assailant. This string of incidents also reminds the Headless Rider of the terror wrought by a certain slasher not too long ago... When people become consumed by their own obsessions, are extreme fans and extreme haters really all that different? Ikebukuro is about to find out!
