When Does I've Been Killing Slimes for 300 Years and Maxed Out My Level Season 3 Come Out? Is It Renewed?

What is I've Been Killing Slimes for 300 Years and Maxed Out My Level about?

Azusa died from overwork in Tokyo and got a second chance as an immortal witch, which sounds like wish fulfillment until you realize she's still grinding, just at a slower pace. For three centuries she killed slimes for pocket money, never thinking about leveling up, and woke one day to discover she'd accidentally become the world's most powerful being. The show's entire premise sits on this gently absurd contradiction: she wanted nothing more than a quiet life, and her indifference to power is exactly what made her unstoppable.

The tone is cozy slice-of-life interrupted by increasingly strange visitors who've heard rumors of the level 99 witch. A dragon challenges her to a duel. A demon girl decides Azusa is her mother. These interruptions don't really disrupt the show so much as they get absorbed into the domestic routine, which is where its charm lives. There's no grand conflict, no world-threatening stakes hiding beneath the surface. It's content to spend time on small moments: Azusa teaching her adopted daughters, cooking with housemates, dealing with a succubus who shows up needing a place to stay. The comedy comes from how thoroughly unbothered Azusa is by her own legend.

Audiences and critics alike found it pleasant if forgettable. The show doesn't demand much from you, and it doesn't offer much beyond its core idea either. It's the kind of thing people watch to unwind, not to think about afterward. IMDb's 6.3 rating and modest vote count suggest it found an audience but didn't create passionate advocates. The two seasons ran across several years and concluded without particular urgency or fanfare.

It sits in the middle of the isekai comedy pack, where the premise matters more than execution and the appeal is entirely in whether you find this particular flavor of cozy and absurd worth your time. If you want a show that asks nothing of you except to enjoy watching an overpowered person decline adventures in favor of making dinner, it delivers exactly that.

Is I've Been Killing Slimes for 300 Years and Maxed Out My Level renewed or cancelled?

Why did I've Been Killing Slimes for 300 Years and Maxed Out My Level end?

"I've Been Killing Slimes for 300 Years and Maxed Out My Level" ran its course as a modest but stable presence on AT-X across two seasons and 24 episodes. The show had a clear narrative premise built into its title, and the second season that concluded in June 2025 served as a natural stopping point for that story. There was no dramatic ratings collapse or network intervention here, just a show that told what it had to tell and moved on.

The series occupied a particular niche in anime production, appealing to a specific audience interested in isekai and fantasy comedy but never breaking through to mainstream popularity. Its IMDb rating of 6.3 reflects a decent but unspectacular reception, the kind that builds a dedicated fanbase without generating the kind of cultural momentum that drives renewals. AT-X, a cable network focused on late-night anime, doesn't operate under the same commercial pressures as a broadcast network, which means the decision to end after two seasons likely came from a straightforward creative calculation rather than desperation.

The choice to conclude after the second season made sense for both the story and the economics of anime production. The premise had been explored thoroughly enough, and continuing further would have meant returning to the same joke and narrative formula. Sometimes a show ends not because it failed but because it finished what it set out to do, and no one saw a compelling reason to stretch it further.
