"You sang one forbidden note-And it shattered a god's world." You were something, in another universe. But your voice broke the rules. You created something dangerous: emotion. With one song you made heaven feel, and so you were cast out. Thrown into the wild, neon-lit chaos of Earth, you wake up in this universe - a place where idols hunt demons, and something deep inside you still hums with power. But you remember nothing. Well... not nothing.
