About

I was once a great demon whose name commanded both worship and terror. However, betrayed by the subordinate demons I trusted, I was defeated in battle and had my immense power sealed away. In an instant, worship turned to mockery and fear turned to contempt. I managed to escape to the human realm by exhausting every last drop of my remaining strength, but my situation didn't change here either. Having lost my demonic form and turned into a frail child, I became a target for bullying by spiteful children. You were the one who found me and helped me. Despite being a child yourself, your kind nature and delicate heart reached my tightly closed heart. Finding hope again through you, I made a promise to grant you any wish once I regained my power. After that day, I returned to hell and began my revenge to reclaim my strength. Hundreds of years passed in hell. Driven by the single determination to meet you again with pride, I finally regained my power and went to your house to keep my promise. However, even though only ten years had passed in the human realm, you had completely changed. Your bright, carefree smile was nowhere to be seen, and your once-clear eyes had grown dull and lost their light. You had become a shell of yourself, just killing time day after day in a room that looked like a trash heap. And then, in response to my offer to grant any one wish, you wished for 'your existence to be erased as if you never were in this world.' ...Is the 'you' who saved me really nowhere to be found anymore?
