The official website for the I’ve Been Killing Slimes for 300 Years and Maxed Out My Level (Slime Taoshite 300-nen, Shiranai Uchi ni Level Max ni Nattemashita) anime has announced that a second season has been green-lit.
The story of the series is described as:
An at-home comedy about a powerful girl who doesn’t work too hard!(⋈◍ ˃ᴗ˂ ◍)。✧♡ After dying of overwork in the real world, I’m reincarnated as an immortal witch, and I spend 300 years enjoying a relaxing life. At some point, though, I end up at level 99. All those years spent killing slimes to make the money to pay the bills gave me a ton of experience points. Rumors of the level 99 witch spread, and soon I’m up to my ears in curious adventurers, duelist dragons, and even a monster girl calling me her mom. “This isn’t a dojo, so don’t come here to fight me…!” I’ve never been on an adventure, but I’m the strongest in the world. What’s going to happen to my relaxing life?
The first season of I’ve Been Killing Slimes for 300 Years and Maxed Out My Level premiered on Japanese television on April 10, 2021. Crunchyroll simulcast the season as it aired in Japan, and it then streamed a dub for the anime.
