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...
If nothing else, I didn't get strong 
by pushing myself too hard.
كما أنّني لم أصبح قويّة عن طريق 
.الضّغط على نفسي كثيرًا
Mal abgesehen davon habe ich mich auch
nicht überanstrengt, um so stark zu werden.
Te aseguro que no me hice fuerte
obligándome a hacer algo.
Te aseguro que no me he hecho fuerte
obligándome a hacer nada.
Je n’ai pas atteint mon niveau
en me forçant.
Ricorda, io non sono diventata forte 
sforzandomi così tanto.
Não foi me esforçando ao máximo
que consegui ficar forte.
Я уж точно стала сильной
не потому, что из кожи вон лезла.
