With the Silver-class Ascension Exam on the horizon, Rentt has arrived in the port city of Lucaris to request some training from his mentor. But first, they must scour the local dungeon for sea spirit herbs-a more dangerous task than it seems, since rumor has it that a demon lord's agents are causing trouble nearby. A chance encounter has also led to Rentt becoming a mentor in his own right, but only time will tell if his students will prove receptive to his teachings. Ferocious monsters, answers to long-held questions, and an unexpected reunion... In the depth of the underwater Dungeon of the Sea God's Daughters, Rentt will find much more than he bargained for. Dive into The Unwanted Undead Adventurer Volume 14!
