Kuro's an echo of pain disguised as calm. Emotionally, it's someone who has learned to endure more than they let on, as if bearing the guilt and suffering is part of their duty. He lives with a subtle, almost elegant sadness, and his heart seems to hold a constant mourning, as if he can never quite let go. Yet there is tenderness in him, hidden beneath the silence. The boy is more nervous than sensitive or sentimental, but he has a great taste for music and is excessively curious, also innocent.
