Sinner the fourth: Nii
Envy's embrace holds him securely. Its siren song whispers the arcane secrets no one else commands, stimulates his innate genius with whispers of haunting inadequacy; forever the hidden one, second-best, less favoured. Delicious, the victories he racks against the one he hates, sweet in his soul. He cannot exist in the presence of light, and he envies its power; letting it spur him, hating its success. He who destroys a thing controls it, and by destroying everything Nii will control everything. With nothing to be compared to, he will reign supreme.
And if he is alone, the voices might stop.
A/N: sorry, PunkWolfIncarnate. But I have decided to take your suggestion; there will be a bonus Kami-sama drabble at the end of this fic. Thanks for the guess, it gave me good inspiration.
