I've Been Killing Slimes for 300 Years and Maxed Out My Level, Vol. 17

I've been killing slimes for 300 years, and now I'm a magical girl?! Natalie and I have been turned into strange, mascot-like creatures, and together we protect the peace of Flatta...Wait, what?! Oh well, I know this is the work of some god or other, so I'm sure we'll soon have it sorted. Then, I accompany Flatorte on her visit home (along with the whole family) and attend Pecora's idol workshop! Finally, Wynona shares an adventure of her own.
