This is the fourth light novel in the Slime Taoshite 300-nen, Shiranai Uchi ni Level Max ni Nattemashita series.
Why do strange things always seem to happen to me?
I've lived in this world killing slimes for three hundred years...so how did I turn into a little kid?! I bet it was those mushrooms Halkara cooked... And now everyone in my family is trying to coddle me! Please cut it out! Not only that, but I have traveling minstrels, a World Spirit Summit, and even a demon music festival to worry about... Still, I'm not giving up on my laid back life.
