The Demonic Competition

In the kingdom of Arceia lived a small prince with talent beyond anything the kingdom had ever seen. He was good at studying, magic, swordsmanship, strategies, anything you could think of. However, he had two major weaknesses. One was his little sister, the first princess of the Arceia kingdom, Elliot Arce. The other was his wife, the princess of the Nevotre kingdom, Olivia Nevo. The only problem was that they were both fated to become villainous demonesses to fight in the underworld. A very large-scale competition between demons that participate in and fight to the death for. The grand prize was respect and reputation, which seemed absurd to Sel Arce, who joined in the competition to protect both his wife and his little sister. Seeing that both were born under royalty and were willing to abandon their titles are princesses for the competition, Sel decided to abandon his humanity and strive to be the strongest magician in order to protect them.
