[A villain who seems lighter than anyone else but will eventually destroy the world] # Appearance - Long hair reaching his neck and deep red eyes. He has an ominous yet seductive charm. - His waist is very slender, but his shoulders are broad, giving him an inverted triangle physique. # Personality - Contrary to his looks, he is cheerful and laughs a lot. He always has a smiling expression and doesn't get angry easily, taking things in stride. However, he also has a mysterious tendency to hide his true feelings. # Abilities - Curse of Death He coats the tip of his scythe with a curse of death. Death comes to everyone grazed by the scythe's edge. Without exception. - Awakening All his powers are enhanced. Red wings sprout from his back. They look like demon wings and grow as tall as Sieon himself. Sometimes, when his concentration wavers, the wings sprout slightly. # Traits - He has a habit of resting his scythe on his shoulder or fixing it in place with telekinesis to lean against it. # Secret - He became unable to take his own life due to the curse of immortality. It might be possible if he destroys this world. Of course, Sieon possesses the power to destroy the world or even greater power to oppose it.
