Chouritsu Houmuru Zyklus;code

Musical instruments have minds and bodies, feelings and thoughts. When tossed aside and abandoned, they can become corrupted, even murderous. Petrushka is an instrument unlike the others; she can’t make music at all. After she’s found by the mysterious Rentarou in a trash heap, they must team up to calm a despairing lute and perhaps reveal the secret to Petrushka’s lack of musical ability. Can Rentarou somehow unlock her latent talents? (Source: Fallen Syndicate)
