Ssulal

About
Ssulal was the third Demon King, a member of the third generation protagonist race and the first Human to become the Demon King, she was selected for the role by Supreme God Planner.

Appearance and Abilities
Visually, she was not too different to a normal human being, she had larger canine teeth than other humans, but this is down to the inherent vampiric nature of the Demon King. Ssulal was certainly vampiric in nature though and natural bloodlust.Physically, she was the weakest Demon King, which meant her thirst for blood was not too strong, when she had the cravings she would have subordinates bring meals to her instead of hunting for her own, as she was constantly concerned about her personal safety.

Instead of fighting, she followed through on intellectual pursuits. Ssulal was a genius, the most intelligent Demon King to ever live, and she put this intellect to good use. After studying the Gods and thinking about how to improve her personal defense, she somehow gained an audience with Supreme God Planner.

After researching the Gods, she found a way to meet with Planner. She put forward her idea, that the Demon King and Dark Lords should have an "Invincibility Field", a skin-tight barrier that cannot be pierced by conventional weaponry, thus shielding the more frail members of the Antagonist Race from physical harm. Planner obliged, but the Invincibility Field came at a price, Demon Kings would no longer have an eternal lifespan, instead serving a fixed term of 1000 years before having to choose a successor.

Unfortunately, Ssulal was the prototype for this new arrangement, and so her term ended after just 500 years instead of the agreed

1000 years, she suddenly melted into the Blood Pool and was never seen again.
