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...
I set aside love, fun, and everything else
وضعت كلّ شيء جانبًا كالحبّ 
.والمرح لأعمل فحسب
Liebe, Spaß und alles andere gab ich auf
und verschrieb mich einzig der Arbeit.
Amor, ocio, etcétera.
Lo dejé todo de lado para trabajar.
Amor, ocio, etcétera.
Lo dejé todo de lado para trabajar.
Amour, loisirs, j’ai tout mis de côté
pour me dévouer à ma société.
Ho messo da parte l'amore, il divertimento 
e qualsiasi altra cosa
Deixei de lado namoro,
diversão e todo o resto de lado
Отказалась от любви,
веселья и всего остального
