I am a slayer who is afraid of monsters. Unexpectedly, I accidentally made a friend, and the domain lord sent me to get rid of a thousand-year-old fox demon in a deep mountain forest. I haven't even scratched the surface of how to eliminate demons, and I'm a coward. But it's hard to deny the domain lord's majesty, so he can only act shamelessly. This trip is destined to be troubled. Fortunately, I met a kind person who was willing to accompany me. He was great and took care of me all the way. Little did I know that he was the cunning fox demon I wanted to deal with!
