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...
That's the world telling you that 
you've done enough for today.

Damit will die Welt dir mitteilen,
dass du für heute genug getan hast.
Es una señal de que el mundo
dice que se acabó por hoy.
