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

I HAVE always been pretty cute... I've been killing slimes for 300 years, and now I'm a magical girl?! Natalie and I have been transformed by 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 get it figured out soon. Anyway, I also accompany Flatorte on her visit home (along with the whole family), and I attend Pecora's idol workshop! Finally, Wynona shares an adventure of her own in another short story spin-off!
