A title inscribed on a Future Stone that Merea discovers and later hidden. It represents a possible future for Merea as a ruler over many demons, akin to a Demon Lord or Demon God. The Future Stone shows a picture of a man with white hair and red eyes sitting on a thorny throne, an image strikingly similar to Merea. This prophecy troubles Merea, as he was raised to be a hero. The 'Lord of a Hundred Demons' is thus a potential dark destiny for the protagonist.
