🎭 What Is I’ve Been Killing Slimes for 300 Years All About?
Hey there! I’m a big anime fan and super excited to help you get into this feel-good isekai 😊
Maybe you’ve seen the title floating around and thought:
“This looks fun… but where do I even start?”
“I heard there’s a second season — is the order confusing?”
If that’s you, don’t worry — I’ve got good news!
This anime has a very simple watch order, which makes it a great pick for newcomers to anime or the isekai genre.
Based on the light novel by Kisetsu Morita, I’ve Been Killing Slimes for 300 Years is a chill and heartwarming fantasy comedy about a former office worker who dies of overwork and gets reincarnated in another world — where she accidentally becomes super powerful after defeating slimes for 300 years 🐌⚡
What starts as a peaceful slow life becomes a hilarious and emotional journey as Azusa (our lovely protagonist) finds herself surrounded by dragons, elves, slime spirits, and more — all of whom slowly become her found family 💕
From Azusa’s kind-hearted nature to the silly-yet-sweet daily adventures of her growing “family,” this show is the perfect dose of comfort anime.
Whether you’re here for wholesome vibes, light fantasy, or just some cute chaos, there’s something to love.

💡 Why This Guide Matters
This guide will walk you through the watch order, share tips on what makes each season shine, and help you stream it in the right place — no confusion, no spoilers, just pure joy. So let’s get started!
🧙♀️ I’ve Been Killing Slimes for 300 Years Watch Order (2025 Updated & Friendly Guide)
If you’re diving into this wholesome and relaxing isekai gem, here’s the best way to watch the anime in the right order. Good news? It’s a simple one — but there’s a good reason for that, and I’ll explain below!
📺 Recommended Watch Order (with Release Dates)
| Order | Title | Format | Air Date |
|---|---|---|---|
| ① | I’ve Been Killing Slimes for 300 Years and Maxed Out My Level | TV Season 1 | Apr–Jun 2021 |
| ② | I’ve Been Killing Slimes for 300 Years and Maxed Out My Level: Season 2 | TV Season 2 | Apr–Jun 2025 |
💡 Why This Order Works Best (And Why It Matters)
This anime follows a lighthearted slice-of-life storyline with occasional emotional beats and plenty of charming character moments. Watching it in broadcast order is also the correct chronological order, and here’s why:
- Season 1 introduces Azusa and builds her family: You meet her adopted daughters, quirky friends, and the warm little world she creates. It’s slow-paced but emotionally rewarding. Jumping ahead would ruin the joy of seeing these relationships bloom organically.
- Season 2 builds on everything: It assumes you already know the characters. Skipping to this season would make the humor and emotional payoffs feel empty — especially with the character growth that quietly happens in Season 1.
🧡 In short: the magic of this anime lies in its simplicity and character bonds. Watching in order lets you grow alongside Azusa and her found family — and trust me, that’s half the fun!
✨ Personal Tip from a Fellow Fan
You could technically watch Season 2 without watching Season 1… but why would you want to miss out on how Laika awkwardly joins Azusa’s family, or how Falfa and Shalsha steal the show as adorable twins? 😄
Plus, some “callback jokes” in Season 2 won’t land if you haven’t seen the earlier episodes. Watching in order doesn’t just make sense — it makes it way more fun.
