Shouzou Saitou and his wife, Ine, have been married for nearly sixty years. Though they have not become wealthy or been able to go on a honeymoon in all that time, their love has remained steadfast. The couple spend their days peacefully tending to an orchard of apple trees and receiving visits from their loving family. While tending to the apple tree they planted on their wedding day, which had snapped in half during a typhoon, the couple notices a golden apple hanging from one of the branches. They decide to eat the apple back at home, and the next morning, the couple awakens to find that they have become young again! In their new but familiar bodies, Shouzou and Ine are able to live life as they never had before: they engage in more modern activities together, such as participating in a sports festival and playing video games. As they revisit the memories of their young love, the romance between them is rekindled, inspiring similar feelings in the younger members of their family.

Kazuma Satou, former NEET and current reincarnated adventurer, finally returns home after the incident at the Crimson Demon village. He is joined by his ever-reliable companions: self-absorbed goddess Aqua, one-trick pony arch-wizard Megumin, and masochistic crusader Lalatina Ford "Darkness" Dustiness. Following their recent exploits, the party is one step closer to vanquishing the Demon King and his armies—a terrifying task that Kazuma is eager to ignore for as long as possible. Things, however, are not going as smoothly as the group would like; they are constantly racking up debt, getting sidetracked during missions, and falling into traps due to their recklessness and eccentricities. As the party struggles with their perennial issues, they receive an invitation from a princess interested in hearing tales of the group's "heroic" deeds. Darkness' pleas to refuse the invitation only fire the others up to accept it, marking the start of yet another uncanny adventure with unforeseen consequences.
