This is a story about a demon king whose soul was split into two on his way from another world to this world.
Conrad: "Although I am your named father, I don't want to be by your side in this capacity."
Junda: "Ah, Your Highness, you are so perfect. I can't forget the first time I saw you. Your black hair and black eyes are so charming, like shining obsidian. Oh, I love you so much, Your Highness."
Paulufram: "We made an engagement from the moment you hit me on the left cheek. You are destined to be mine. Don't even think about running away."
Guyindalu: "I'll take the dolphin you gave me as a token of love. I'll give you this little bear. That's how we exchanged it."
Great Sage (Ten Murata): "At first, I approached you just to help you complete the task better, but after getting along with me, my heart seemed to have rebelled and was out of my control. Can you come and treat me?"
True King: "As expected of my chosen Demon King, you are so powerful and charming that even I fell into your tenderness without knowing it."
