Card Lores:Sorrow Masquerade, Nero

He has concealed himself in the luxurious room at the top floor of the Shade Artificial mansion. You will not see him being anywhere outside of that room except at the dining table when there's a big meeting or party. However, he never speaks anything in front of anyone. Everyone knows him as the one who possesses, rules, and is the owner of the mansion, one who they must respect. That sums up, no one actually tries to approach him at all. No one knows what's behind the put-up smile of his, nor even realizes it. The reason he conceals himself from the outside world is left to be a mystery, as he suffers from a past of his own.
