I've Been Killing Slimes for 300 Years and Maxed Out My Level, Vol. 18

LAIKA'S A DRAGON LORD?!Well, technically, she did win a huge competition to decide that a while ago. Now it seems she intends to meet the dragon race's various masters and fight them to grow stronger... Halkara's sister also pays the highlands a visit, I get shrunk down (again), and we take a journey to the bottom of the sea! And, of course, Laika's adventures at the Red-Dragon Academy continue!
