The Devil is a Part-Timer?!

BOOM BABY!!! (Y/N) (L/N) here, and if you thought the last books couldn't get even more crazier and epic than before, then BOY YOU'RE IN FOR A TREAT! From several new adventures, new girls, and probably some of the biggest threats I'll ever take on, boy this is going to be great! And did I mention, I'll be working with more heroes from now on? Including this kid who has a watch that lets him turn into aliens. Yeah, it's going to be one of those types of adventures again. Sheesh, if I have to work with others who are my age, I don't know what I'm going to do.
