Akame Ga Kill: The Tusk Of Darkness

Once upon a time, the most evil being known to mankind, a demon king who was granted a body that was a mockery to life itself, took on a Golden Knight and his companions, but, he had fallen in battle.

For what it seemed like a lifetime, he floated in darkness, until...he was one day reincarnated as the one thing he hated most: Light.

Of his past, he knows nothing. But....he will come to know despair....and hope, for even darkness can shine brighter than light.

And now, once again, the Dark Knight marches forth, with fangs bared at the bloody corrupted world that he was reborn in.
