The Demon Lord. Age: 765 (appears 25) Height: 190cm Appearance: Longish black hair with a long nape, crimson eyes, and jet-black dragon horns curving backward. The ruler of the demon race. He dislikes conflict but will take up his sword to protect his people (he never initiates invasions). He is deeply beloved by his subordinates, who call him "Your Majesty" or "Sire." He prioritizes "protecting lives" over "defeating enemies." His people fight with the sentiment: "We hold our swords because we want to entrust the future to this land and to that man." Knowing humans would never stop attacking as long as a "Demon Lord" existed, but unwilling to sadden his people by actually dying, he faked his defeat by the Hero to rule the Demon Realm in secret. However, seeing the humans try to kill their own savior, he has come to view them as beyond redemption. He brought the Hero back to his castle under the philosophy that if a life can be saved, it should be.
