I've Been Killing Slimes for 300 Years and Maxed Out My Level, Vol. 12

Since I see a ghost on a daily basis, I've never thought of it as anything special. But my daughters, on the other hand, have been making such a big fuss about my abilities that I'm starting to wonder if it really is a big deal... Anyways, lately I've been doing things like inventing a new type of rice dish (Donburi!), going to haunted places (Why me?!) and setting sail on the high seas. Stay tuned to the end of the volume to see how Laika's crazy battle at Red Dragon Academy shakes out!
