Aizawa Azusa, a corporate drone who died of exhaustion from overwork in her previous life, is reincarnated in another world, where she decides to live out a slow and uneventful life forever. But then, 300 years later, she discovers that the experience she earned by defeating slimes every day just to keep up her easy lifestyle has brought her to level 99 and made her the strongest in the world. The rumors begin to spread, and soon trouble comes knocking...
and when I feel like getting some 
exercise, I beat up slimes!
،وعندما أشعر أنّ عليّ التّمرّن قليلاً
!أخرج لهزيمة الهُلاميّات
und wenn ich mich ein wenig ertüchtigen
möchte, vermöble ich Schleime!
Cazaba slimes para hacer ejercicio.
Cazaba slimes para hacer ejercicio.
et je chasse les slimes
en guise d’exercice !
e quando mi va di fare esercizio, 
sconfiggo gli slime!
E, quando quero me exercitar,
eu acabo com uns slimes!
и бью слизь, когда хочу размяться!
