Slime Taoshite 300-nen, Shiranai Uchi ni Level MAX ni Nattemashita

In Slime Taoshite 300-nen, Shiranai Uchi ni Level MAX ni Nattemashita, a woman who died from overwork is reborn as an immortal witch named Azusa. She vows to live a peaceful, stress-free life in the countryside, earning a modest living by defeating low-level slimes. However, after 300 years of this simple routine, she discovers she has inadvertently reached the maximum possible level, becoming the world's most powerful being.

The anime is a charming iyashikei (healing) comedy that follows Azusa as her hard-earned solitude is disrupted by a parade of eccentric visitors. From awestruck adventurers and proud dragons to affectionate monster girls, her quiet home becomes an unexpected hub for those drawn to her legendary strength. The core of the anime lies in Azusa's comedic struggle to protect her lazy, ideal lifestyle while reluctantly forming a unique and warm-hearted family with those who gather around her.
