Synopsis
In the shadow of his famous detective brother Kiyotaka, Ayumu Narumi has always felt overshadowed. Two years after Kiyotaka's disappearance—which left behind only cryptic clues about the "Blade Children"—Ayumu is suddenly drawn into a far darker mystery. When a student at his school is found dead in what appears to be a suicide, the case quickly turns into a murder investigation, and Ayumu becomes the prime suspect. Determined to clear his name, he digs deeper into the case and finds himself entangled with the elusive Blade Children. These individuals seem to have a significant connection to Kiyotaka, and as Ayumu investigates further, he uncovers the grave threat they pose—and learns that his relationship with his brother is far more intricate and perilous than he ever imagined.
