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...
Laika, you just said you'd 
work all night, didn't you?
لايكا، قلتِ للتّوّ أنّك ستعملين طوال اللّيل، صحيح؟
Laika, du meintest doch gerade,
du würdest die ganze Nacht durcharbeiten.
¿Pensabas trabajar toda la noche
sin dormir, Laika?
¿Pensabas trabajar toda la noche
sin dormir, Laika?
Raika, tu étais prête
à passer la nuit à travailler.
Laika, hai appena detto che 
vuoi lavorare tutta la notte, o sbaglio?
Laika, você acabou de dizer que
trabalharia a noite toda, não disse?
Лайка. Говоришь,
всю ночь проработаешь?
