I've Been Killing Slimes for 300 Years and Maxed Out My Level Novel Volume 13 is written by Kisetsu Morita with illustrations by Benio.

I’ve been killing slimes for 300 years, and now I’m finally going to meet the Grim Reaper?! She seemed like totally bad news, so I wasn’t too thrilled at the prospect…but it turns out that she’s sort of like a goddess?!

Besides that, I also went on a trip to the demon lands with Pecora (it was kinda Romantic★) and cleared a video game world created by the gods (games from another world, you say?). Plus, Halkara accepted challenge from a “phantom thief.”

Stick around till the end to find out more about Laika’s wacky battles at the Red-Dragon Academy for Girls!
