Demon King (Queen)

The Demon King, also translated as Demon Queen or Maou, is the main female protagonist and the 43rd Demon King, the epithet "Ruby Eyes," the supreme ruler of the Demon Realm. After teaming up with the Hero, she disguises herself as a human noblewoman known as the Crimson Scholar and shares her vast knowledge on such topics as economics and farming. She comes from the Library Clan, a clan of demons that prioritize knowledge. They reside in a hidden dimension called the Exterior Library, which contains a vast archive of knowledge from various times and alternate universes. Instead of a desire to conquer the human realm, she instead wants to see the "other side of the hill," a world where both the humans and the demons were freed from war. The Demon King is a woman of average height. She has (detachable) horns and long, flowing red hair reaching some way down past her shoulders. Like her hair, she has deep, ruby-colored eyes reflected in her epithet, Ruby Eyes. Even though she has a young woman's appearance, she is over a hundred years old. Her Demon King outfit, forced on her by Senior Maid, consists of a long, red dress that reaches down to her feet. The dress's low-cut collar reveals her ample cleavage, which she vocally disapproves of. This robe has a fur collar, similar to a boa, and a red diamond pattern running along its black sleeves. The Demon King is generally easy-going, cheerful, and relaxed. When the Hero barges into her throne room to kill her, she greets him with a disarming "Hello!" and a curtsy, which throws him off and quickly makes him lose his will to strike her down. She is a bit sensitive about her massive breasts, which the Senior Maid often makes fun of. By extension, she dislikes wearing the revealing clothing that the senior maid forced on her and would rather don casual, modest attire. Despite this, she also displays a lack of modesty when she nearly exposes her breasts to Hero to show off the Demon Mark, proof that she truly is the Demon King. Though an imposing and intelligent woman, she has shown a bit of a childish and comedic side.
