Series will premiere sometime in 2025. I haven’t found an English article yet with additional information, but the Natalie article is here if you want to give DeepL a go. Synopsis of the first season from AniList:
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?!

I am personally excited for this one as it is one of my favorite “slow isekai” series in anime form. I read many others in the genre in manga, but all of them that have been adapted into anime have just not been great. This is one of the few that I have really enjoyed in anime form as well.
This was such a chill Isekai, so glad it’s getting a second season.
