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...
But it matters not how 
advanced your magic is!

Ma non importa quanto sia avanzata la tua magia!
Mas a força da sua magia
não faz diferença!
Но неважно, сколь
сильна твоя магия!
