Aku No Fuhai Kage

When a 2000 year old sickness returns from the dead and corrupts everybody in it's sight, only a few people have managed to fight it off. However.. some weren't so lucky.. some were killed.
But who's going put a stop to it and how will they do it? Will they even do it in time or will they get killed before they even get the chance?

Warning: The story will mention blood, graphic scenes, suicide, etc.
