Synopsis:

Azusa Aizawa, weary from a life of corporate drudgery, finds herself reborn in a fantastical world with an unusual destiny. Granted immortality by a goddess, she settles into a quiet existence of farming and village protection, her days punctuated by the repetitive task of defeating slimes – a seemingly unremarkable endeavor pursued for centuries.

However, Azusa's consistent battles have propelled her to unprecedented power, reaching the theoretical peak level in the game's system. This extraordinary strength attracts attention, drawing a diverse cast of characters from across the continent. As rumors of her abilities spread, Azusa is confronted with requests for aid and challenges to her peaceful routine. The narrative explores themes of isolation versus connection, and the unexpected bonds forged through shared experiences, as Azusa navigates a world that demands more than she ever anticipated.
