A man who died from overwork at his job is reborn as Noctis, a frail noble lord. Determined to avoid working in his new life, he faces challenges as his territory remains impoverished due to constant monster attacks from a vast forest.

After a demonic assault leaves him and his brother as the only survivors, Noctis, who values order and cleanliness, aims to build a future where hard labor is unnecessary.
