Few isekai series lean into comfort the way I’ve Been Killing Slimes for 300 Years and Maxed Out My Level (Slime Taoshite 300-nen, Shiranai Uchi ni Level Max ni Nattemashita) does. Instead of chasing escalating power or high-stakes conflict, the anime builds its charm around routine, found family, and the quiet joy of living slowly. After Season 2 wrapped up in mid-2025, attention has naturally shifted toward what the future holds for Azusa and her ever-growing household.
With the light novel series approaching its conclusion and the anime maintaining steady popularity, Season 3 remains a realistic possibility. Here’s a clear breakdown of where the story stands, what could come next, and why fans are still invested.
Seasons Recap
The anime began with Season 1, animated by Revoroot, which aired from April to June 2021. Across 12 episodes, it established the series’ defining tone: low-stress fantasy, gentle humor, and character-driven storytelling.
Season 2, produced by Studio Teddy, aired from April to June 2025 and delivered another 12 episodes. While the structure stayed familiar, the season expanded Azusa’s world, introduced new characters, and leaned further into emotional warmth rather than plot escalation. Across both seasons, the anime has released 24 episodes, all centered on consistency rather than reinvention.
The Story So Far: Why Azusa’s World Still Works
Azusa Aizawa dies young after years of overwork and reincarnates as an immortal witch. Determined never to repeat her past life, she chooses a quiet existence in the highlands. Over 300 years of casually defeating slimes, however, accidentally pushes her to max level.
Rather than turning that power into conquest, Azusa builds a family. Slime spirits Falfa and Shalsha become her daughters. Dragon girl Laika joins as a disciple. Demon official Beelzebub, elf inventor Halkara, and several others slowly form a household built on acceptance rather than ambition.
Season 2 focused more on travel, emotional bonding, and small disruptions to Azusa’s peaceful routine. The anime consistently reinforced its central theme: strength doesn’t have to lead to conflict.
I’ve Been Killing Slimes for 300 Years and Maxed Out My Level Season 3 Release Date
As of early 2026, I’ve been killing slimes for 300 years and maxed out my level season 3 has not been officially confirmed. Season 2 concluded in June 2025 without a renewal announcement.
However, several factors keep expectations alive. The light novel series is nearing its planned conclusion, which often prompts anime committees to consider final or continuation seasons. Additionally, the anime maintains solid streaming performance and stable fan engagement. If a renewal happens, a 2027 release window feels realistic based on prior production gaps.
Potential Story Direction for I’ve been killing slimes for 300 years and maxed out my level season 3
A third season would likely continue adapting the mid-to-later light novel volumes. The tone would remain unchanged, but the scope could widen slightly. Possible focuses include deeper exploration of Azusa’s immortality, more cross-realm interactions, and expanded roles for secondary characters. Family-centric storytelling would remain the core, with comedy arising from misunderstandings, magical inconveniences, and Azusa’s constant attempts to avoid responsibility.
Importantly, the series shows no signs of abandoning its low-stakes identity.
Ratings and Audience Reception
The anime continues to hold steady ratings across platforms:
- IMDb: 6.3/10
- MyAnimeList: 6.89/10
Viewers frequently praise the series for its calming tone and character chemistry. Criticism typically centers on repetition, though many fans view that consistency as a strength rather than a flaw.
Cast Expectations If Season 3 Happens
The core voice cast is expected to return if production moves forward. That includes Aoi Yuuki as Azusa, Kaede Hondo as Laika, Sayaka Senbongi as Falfa, and Minami Tanaka as Shalsha. Both the Japanese and English casts have been a major part of the anime’s relaxed atmosphere, and no changes are anticipated.
Where to Watch the Series
Both seasons are currently available on Crunchyroll with subbed and dubbed options. Additional availability varies by region, including select access through Prime Video.
About The Anime

The novels began in 2016 and are scheduled to conclude with Volume 30 in 2026. A manga adaptation by Yusuke Shiba is also ongoing.

Final Thoughts
I’ve Been Killing Slimes for 300 Years and Maxed Out My Level succeeds because it never tries to be louder than it needs to be. Its strength lies in routine, comfort, and character relationships that grow naturally over time.
Season 3 remains unconfirmed, but the story’s structure, source material status, and audience support leave the door open. Until then, Azusa’s slow life continues to resonate as a reminder that sometimes, doing less is the real fantasy. Stay Tuned to TheAnimeDaily for the latest news and updates.
