Summoning of Shadow Demon King
In the sky, Sun could be seen covered in clouds; The light passing through it fell on the one-kilometer area, making it look like there was a day, but the rest of the area, was still filled with darkness. A boy could be seen making a giant circle; he then drew a pentagram inside it. He then used his shadow energy to create a sculpture of the head of a goat-headed demon.
He then took out large candles and placed them around the circle before lighting them up; He then brought out a humanoid beast covered in chains. He struggled constantly, but the boy ignored him and brought him to the center of the circle in front of the skull.
He then started chanting the incantation, "Suscipe, rex daemon, sacrificium meum et Ostende te!" He cut out his thumb and used it to mark the forehead of the creature; he then marked the forehead of the skull. He then looked at the sunlight around him and snapped.
