The story follows Subaru Natsuki, a hikikomori who is suddenly transported to another world on his way home from a convenience store. Lacking any combat ability, the power he gains instead is "Return by Death," which sends him back in time to a certain point whenever he dies, forcing him to relive events in search of a way to save the people around him.

Unlike many isekai stories built around a protagonist who overwhelms every obstacle, this series is known for having its protagonist repeatedly face death and despair while struggling to find solutions through trial and error. The isolation and psychological toll of being unable to share his ability with others add weight beyond simple entertainment. The series is valued for its distinctive cast of characters, its richly detailed world, and its unpredictable plot developments, which have inspired a wide range of fan works exploring different characters and settings in depth.
