I've Been Killing Slimes for 300 Years and Maxed Out My Level, Vol. 17 takes an unexpected turn as I find myself turned into a magical girl! Together with Natalie, we are transformed into strange, mascot-like creatures, charged with the mission of protecting the peace of Flatta... Wait, what?!

This bizarre twist of fate seems to be the handiwork of some god or other, so I'm confident we'll have everything sorted soon enough. Meanwhile, I join Flatorte on her visit home, bringing along the whole family, and attend Pecora's idol workshop!

To cap it all off, Wynona shares an adventure of her own, adding another layer of excitement to our unusual journey.
