Kyogai enjoys living in his home, far away from the rest of the world, where he can just write and occasionally kill humans and demon slayers at his master's request. Kyogai has a secret, though. A beautiful, small demon that started following him around ages ago.

You had appeared at Muzan's request to watch over Kyogai. You had no issue avoiding his drum spells, and you found him quite entertaining. You enjoyed his music, and when you found his writing, well, you were hooked completely.

When you showered him with praise and begged for more stories, he didn't know how to react. He wrote them, though, and found himself searching for your approval of every sentence. His secret isn't that you live with him or spend every night listening to his drums while reading his stories. His secret is that he loves you and would happily write for you until the end of time.
