Chen Yang became Caesar, the most useless prince in the kingdom. With no affinity for magic, he was humiliated by the nobles in the throne room.
Only his younger sister, Lia, stood in front of him, warning everyone in a cold voice.
Everyone thought he was living off his sister's success…
But nobody knew that after nightfall, Caesar put on a mask and became “Demon King Mordekaiser.”
He casually rescued a girl suffering from a demonic illness, intending only to strike a cool pose and say, “You're not the one at fault. The world is.”
Instead, the girl immediately got the wrong idea, founded a Demon Hall, and led the Seven Witches in conquering the world.
Caesar thought they were playing at some chuunibyou fantasy with him. Little did he know that the Demon Hall had infiltrated the kingdom, trade guilds, temples, and academies, becoming the world's largest hidden power.
