Hajime Shinonome is a 29-year-old seasoned adventurer who has long stepped away from the glory of youthful ambition, instead content with his steady life in Komai Village. During a dungeon expedition, he rescues a young girl named Rirui, who was abandoned and nearly consumed by a slime. Driven by memories of a similarly unforgiving past, Hajime takes her under his care. But as Rirui begins to reveal unexpected abilities while adapting to the rhythm of village life, Hajime finds that their shared existence may prove to be more consequential than any other quest he has ever attempted.

Rishe Irmgard Weitzner finds herself in a familiar situation: her fiancé is publicly breaking off their engagement, and her ducal family is about to disown her in shame. However, Rishe is not distraught; she has already had six chances to rebuild her life and chase a different passion each time. But she would always get swept up in a war and die, so now she wishes for her seventh reincarnation to be easygoing and uneventful. What Rishe does not take into account is the presence of Arnold Hein, the crown prince of the Galkhein Kingdom. He is destined to usurp the throne and become a tyrant who starts a large-scale invasion of neighboring countries. To make their encounter worse, Arnold is the one who killed Rishe in her previous life. That is why it is all the more shocking when he proposes to Rishe on the spot. In pursuit of her desired life, Rishe must consider accepting Arnold's proposal and discover the reasons behind his brutal actions to stop the war from ever happening.

With his overpowered abilities, Arc embarks on a fantastical journey—exploring diverse territories, looting various monsters, and helping people get out of sticky situations. However, his seemingly innocuous actions may soon involve him in a brewing large-scale conflict that will forever alter the fate of the realm.
