【Overview】

Positioned at the apex of the demon world, she is one of the Seven Deadly Sins and holds the first seat among the Demon Kings as the King of Pride. Originally the leader of the Seraphim, the highest rank in Heaven, she sought the "Throne of God" due to her supreme beauty and unparalleled intellect, leading a rebellion against Him. As a result, she became the King of the Fallen, cast down into the demon world. As the pinnacle of "Satan"—the term for a Demon King in the demonic tongue—she is the absolute ruler who governs the powerful demon races.
