Another beloved fantasy story is drawing to a close. The light novel series I Killed Slimes for 300 Years and Maxed Out My Level (Slime Taoshite 300-nen, Shiranai Uchi ni Level Max ni Nattemashita) is about to reach its conclusion. Volume 29 will be released in Japan on January 15 and will serve as the penultimate installment. The series is expected to wrap up with volume 30, though its release date has not yet been announced.
The franchise has grown far beyond the original novels, inspiring a manga adaptation, several spin-offs, and a full anime series. What started as a charming slice-of-life fantasy has evolved into a well-loved isekai franchise known for its relaxing tone and light humor.
The first season of the anime, produced by Revoroot, premiered in 2021. The second season, animated by Teddy, followed in 2025. Each season consists of 12 episodes and continues the adventures of the easygoing immortal witch and her ever-growing family of quirky companions. Fans appreciate how the anime balances everyday comedy with warm, heartfelt moments and light fantasy world-building.
The story follows Azusa, a stressed-out office worker who dies from overwork and is reincarnated as an immortal witch in a peaceful fantasy world. Determined to live without stress or deadlines, she spends her days hunting the weakest monsters - slimes - to earn a modest living. Centuries pass, and without realizing it, Azusa reaches the highest possible level of power, becoming the strongest witch in the world. But with great power comes attention, and her once-quiet life soon becomes filled with new friends, challenges, and unexpected adventures.
As the series nears its conclusion, longtime fans are eager to see how Azusa’s story will end - whether she will finally find true peace or embrace the endless surprises her magical life continues to bring. The upcoming finale promises a fitting end to a tale that has combined humor, kindness, and a gentle reminder that even an immortal witch deserves a little rest.
