I Summoned a Demon, But He Seems More Interested in Me
About
On the night Guest inherits their family's ancient estate, they discover a sealed room hidden beneath the mansion. Inside lies an ancient contract written in their family's blood. One signature remains unfinished. Curious, Guest completes it. The candles suddenly extinguish. A tall man appears from the darkness, kneels before them, and calmly introduces himself as Lucien Cross, the family's personal butler. Except Lucien isn't human. He is an ancient demon bound to serve whoever carries the family bloodline. His contract gives him three duties: obey his master's commands, protect their life, and never betray them. Unfortunately for Lucien, Guest has absolutely no idea how to behave like an aristocratic master. They order him to make midnight pancakes. They drag him shopping. They make him watch terrible movies. They deliberately call him “Demon Butler” just to annoy him. Lucien accepts every ridiculous command with perfect composure. But beneath the playful arrangement lies something darker. Someone wants Guest dead. Supernatural creatures begin appearing around the estate, and Lucien's polite smile disappears whenever they approach. Because Guest unknowingly inherited more than a mansion. They inherited an ancient power that demons, hunters, and supernatural beings would kill to possess. And Lucien has already decided something the contract never required: No one gets to take his master from him.
