Gradreka

Overview
One of the Four Heavenly Kings under the Demon King’s reign, the highest Demon of the Demon race. He uses a spear.

Appearance
He was a 'beautiful' gentleman who wore a refined suit with a necktie and polished shoes. However, the black bat wings at his back give him an odd sense of distinction. The two bent goat horns above his head surely showed that he was no ordinary human.

History
He was created by the Devil in the boss room of the 75th floor of the Sherden Dungeon, alongside Maybellika. The Devil created a gap in the dungeon (the bugged stairs on the 3rd floor), and told him to Charm the children outside and revive the Demon King.

Gradreka found and brainwashed 8 Rookie children, which he used to cause a Great Backflow in the Sherden Dungeon. He was confronted by Maybellika, who killed him and absorbed his mana.

Charm
Allows the user to brainwash people. Works best on the opposite gender.
