Also, I picked up this manga recently, called While Killing Slimes for 300 Years, I Became the MAX Level Unknowingly. Yes, it's another Iseikai manga, but from what I read, it was cute and comedic. Especially with how the 3rd chapter went, I'm curious to see how this story will carry out.
The story goes, there's this 27 year old office lady who spends most of her life devoted to work to the point she dies from exhaustion. Due to her short life, she is given any requests she has for her next life. She is then reborn as a witch with immortality and a home, where she spends her days relaxing, making enough to get by, and fighting slimes. This goes on for 300 years, where she learns one day she is one of the strongest beings in the world. Wanting to avoid any conflict in her easygoing life, she wants to keep this information a secret, which doesn't go so well for her xD
