Henry Tone, an adventurer who came to the city behind from the front line of the battle with the Demon King.

His purpose is……

“I want to spend the rest of my life by thinning out lukewarm monsters in a safe city and collecting materials in places where I can go for an excursion.”

It’s a story of a peaceful life spent by a man who, at around twenty years old, no longer shows any signs of ambition.
