Season 1 Plot

After many years of being a corporate slave, Azusa Aizawa abruptly passes away due to severe exhaustion. Seemingly headed for the afterlife, she meets a goddess who bestows her with immortality alongside a peaceful life in another world. There, Azusa enjoys her days tending to her farm, protecting the nearby village, and killing about 25 slimes per day—a routine that continues for at least three centuries. However, this rather monotonous cycle begins to change when Azusa suddenly finds out that she has reached level 99—the maximum possible level—from slimes alone. Despite desperately trying to hide this fact in fear of ending her slow life, rumors of her strength spread nevertheless. Soon enough, various people throughout the continent, start to appear at her doorstep—some seeking a battle, others asking for her assistance. Meeting friends and acquaintances who soon become family, Azusa finds she can live a life far better with others than when she was alone.

I've Been Killing Slimes for 300 Years and Maxed Out My Level Season 1 aired on April 10th, 2021.

June 12th, 202124 min

One day, a girl with rabbit ears comes to the village of Flatta. This nameless, unpopular minstrel, who strums her lute fiercely with her bare fingers and sings with a death growl, is known as Schifanoia. When she passes out in the middle of her concert, Azusa is reminded of the sad stories she's heard of young men who moved to Tokyo hoping to make their major debut, but instead turn into job-hopping middle-aged men playing in bands that never make any profit. So she invites Schifanoia to live at the house in the highlands for a while, but when she just keeps making excuses and refuses to see reality, Flatorte loses her patience...

11. I Ate a Mushroom and Turned Into a Child

June 19th, 202124 min

Halkara throws a mushroom-grilling party, or "shroompa" for short, and accidently includes some poisonous mushrooms that cause anyone who eats them to shrink... and Azusa eats one.

Azusa is determined to change back to normal, so after a tip from Pecora, she heads to the World Tree along with Fatla and Vania to find a pharmacist who deals in every kind of medicine. She expects a dungeon with 108 floors to fight through, but...

Festival season has come to the village of Flatta. The festival has been held there for the past 250 years, but as the only person who knows its entire history since it was started, Azusa has distanced herself from it to let the villagers keep their independence. But her family has shown interest in it and seems excited to see it, so she makes up her mind to change the way she interacts with the village tradition... and thus the one-day-only coffee shop, The Witch's House, was born. Will the villagers enjoy this little shop Azusa's family has created?
