Ordinary office lady Azusa Aizawa died due to overwork. For that reason, when she finds herself reborn as an immortal witch with the appearance of a 17-year-old, she decides to live an easy-going life. Her main source of income is collecting magic stones that drop off the slimes that live in the nearby forest and selling them at the nearby village's guild. After doing this for the last 300 years, she's unknowingly become a level 99 witch, the most powerful of all.

I have an interesting adventure trying to find this story. So for the longest time this didn't have any English translations with the only ones i'm able to find is the Raw's, Brazilian and some weird language i'v never heard of. I finally found it and i love it.

It's nothing ground breaking or new. But it doesn't have to be. I find that the MC herself is more then enough for me to like this.

I mean it's not particularly bad, it's just not very good either.
So what I'm saying is you might enjoy this if you like cute-girls-doing-cute-things / moe-blob shows.

Story: 4/10
Unaging girl has been getting ~50 exp every day for the past 300 years, so now she's max level and very powerful, but she doesn't care, all she wants to do is laze around peacefully. We've had more or less 3 arc now and all of them have gone more or less like this:
> Knock knock on the door.
> A X shows, lighty bothering Main-character-chan and demonstrating/announcing a problem to come.
> Some time passes.
> Problem to come shows read more

I really wanted to love this manga, and when reading the summary of it and the first few chapters I really did. In fact, that initial enjoyment made me give this a 9 for the longest time and is also the biggest reason for why I’m now writing a review. However, ‘I’ve Been Killing Slimes for 300 Years and Maxes Out my Level’ changed as the manga went on and went from more of a relaxing, slow paced story about a girl, after dying from overworking, who wants a redo of life and to enjoy it and her struggles to maintain that quiet, peaceful life, read more
