I've Been Killing Slimes for 300 Years and Maxed Out My Level

After a life of corporate drudgery cut tragically short, one woman's greatest wish for her next life is a peaceful, uneventful existence. Reborn as an immortal witch in a fantasy world, Azusa is granted her wish — or so she thinks. For three centuries, she dedicates herself to a quiet life of potion-making, her only "work" defeating the weakest of monsters: slimes. Yet, even the most mundane routines can lead to extraordinary outcomes. When news of an all-powerful "Witch of the Highlands" spreads, Azusa discovers her casual slime-slaying has inadvertently maxed out her level, making her the strongest being in the land. Now, her once-tranquil life is anything but, as adventurers, dragons, and demons come calling, eager to challenge her or simply bask in her accidental glory. Can this unassuming witch maintain her peaceful existence amidst the chaos of her newfound fame?
