THE HAUNTING MELODY OF DEATH Class Q is tasked with investigating a chilling threat sent to a violin teacher—a letter from genius violinist Hosho Mitsuru, who supposedly committed suicide six months ago. Kyuu and his friends travel to Gensoukan, only to be pulled into a deadly game when a series of murders unfold, all tied to the legendary violin Testa di Drago crafted by Kuzuryu Takumi. The haunting strains of "Devil’s Trill," played by the so-called "Maestro of the Underworld," echo through the mountain lodge, casting suspicion even on Ryu. As the body count rises, the sinister hand of Pluto seems to be orchestrating the chaos—can Class Q uncover the killer before the final note is played?
