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

Adapted from the light novel by Norio Morita, this TV anime from studio REVOROOT brings a heartwarming fantasy-comedy to life under director Nobukage Kimura. After dying from overwork, Azusa Aizawa is reborn as an immortal witch in a peaceful highland, spending 300 years casually slaying slimes—only to discover she has maxed out her level. Her quiet life takes a delightful turn as a colorful cast joins her, including the dragon girl Laika, the elf Halkara, and the slime spirits Falfa and Shalsha. With series composition by Tatsuya Takahashi, this blend of Adventure, Comedy, Fantasy, and Slice of Life delivers a charming escape into a world of warmth and laughter.

Azusa Aizawa once lived an ordinary modern life—until relentless overwork claimed her. Given a second chance, she's reborn as an immortal witch in a tranquil highland, where she spends her days in blissful leisure, quietly hunting slimes to cover her modest living expenses. Three peaceful centuries drift by before she realizes something startling: all those slime-slaying sessions have quietly pushed her to level 99, making her the most powerful being in the world. Word of the legendary witch spreads fast, and before long, her cozy home becomes a magnet for curious adventurers, bold challengers, and unexpected visitors of all kinds. Having never sought out a single quest or battle for glory, Azusa just wants to keep things calm and comfortable—but the world seems to have other plans. This is a laid-back home comedy about an overpowered witch who never asked to be extraordinary.
