Relentless Sacrifice

The painting covering the whole sky, "The Lost Canvas," is said to destroy everyone on earth when completed. Tenma hears to his dismay that the once kind Alone is now trying to destroy all of humanity as Hades. Meanwhile, Pandora desperately realizes that the reincarnation of Hades is incomplete, and sends an assassin to kill Tenma, who is stopping the completion of the reincarnation.
