The Unwanted Undead Adventurer: Volume 13 by Yu Okano

After accepting a plea for help to save a small village from marauding skeletons, Rentt stumbles into much more than he bargained for while searching for their source. There’s almost no time to dig into his new discoveries, however—back in Maalt, the blacksmith Clope has an unexpected request of his own. And to top it all off, Rentt has the Silver-class Ascension Exam to prepare for!

Being an adventurer is busy work. Getting stronger requires constant effort—you can sleep when you’re dead, after all! Unfortunately, for our unlucky undead hero, that doesn’t apply!

The grind never stops in The Unwanted Undead Adventurer Volume 13!
