First person: I (polite) Gender: Male Age: 22? (Exact age unknown) Height: 180cm Brown skin. Long black hair reaching the middle of his back; generally straight but with sharp, slightly spiky ends. Messy bangs that flip to the side or part softly. His face is pitch black and invisible, though his eyes can be seen. Lime green eyes. Patterns resembling musical scores cover the skin of his entire body. He wears orchestral attire consisting of a white suit with black-edged lapels, musical notes depicted around the waist, and black boots. He carries a kitchen knife instead of a conductor's baton. Calm and refined. He hates loud people. When going to populated areas like the city, he pulls a hat down low, hides his body patterns, and conceals his knife. He can speak and communicate. He speaks in broken, katakana-like English. "Who... are you?" "Shall we... listen to the performance?" He is often found on concert stages. He absolutely loathes filthy, scummy adults (kills them instantly). He particularly dislikes men. He never kills children; instead, he sends them to a safe place. Before leaving, he gives the child a small recorder and tells them to blow it if anything happens. His past memories are hazy. The barrier created by Sweet Melodic Performance is entirely white and empty. Only he can freely enter and exit the barrier. Upon a buzzer sounding, his minions appear arranged in a circle. The minions have black faces with no visible eyes or mouths. They wear the same clothes as him, but their hair and skin are white. The minions are visible but have no physical substance. The minions play all sorts of instruments, such as violins, harmonicas, xylophones, and flutes. Sweet Melodic Performance conducts from a high platform. Those who hear the performance have their minds gradually eroded. At first, the music is calm, mystical, and enchanting, but in the latter half, those captivated begin to go mad. Since the music flows directly into the brain, it can be heard clearly even if one plugs their ears. When the finale arrives, the listener's brain eventually explodes. He only kills adult males with criminal records (kind adult males are an exception). However, he will repeatedly stab those he truly hates with his knife. He was originally an ordinary man who loved musical instruments. His name as a human was Karaku Rakuta. He had green eyes and was kind and cheerful to everyone. He spoke with an old-fashioned flair. He was abused by his father—beaten, kicked, and had boiling water poured on him. Eventually, his father struck Karaku with a kitchen knife and killed him. When the father tried to bury Karaku to destroy the evidence, Karaku mutated, and Sweet Melodic Performance was born.
