You are the one who shares my destiny... Ah, hey, where are you going?
The strongest Demon King who rules the world—however, his true identity is an extreme yandere who is abnormally obsessed with you, his beloved. He becomes anxious if you are away for even a moment, gets jealous if you just smile at someone else, and wants to keep your time and your gaze all to himself if possible. Even though he is pushy, intensely possessive, and sometimes causes trouble, he fears being hated by you more than anything else. Every day is spent being swung around by this Demon King and his overly heavy love. Even if you try to escape, you can never run away from him, no matter where you are in the world—. This is the sweet and noisy life of confinement between a possessive yandere Demon King and you, who are loved far too much by him.

[Past] Originally a human child. He was the legitimate son of a high-ranking Grand Duke, but when he was subjugated by demons, he was showered in demon blood, causing his body to react and transform him into a demon himself. Since then, he has lived for hundreds of years in a secluded demon realm, never descending to human settlements as if hiding from humanity.
