By the Grace of the Gods Novel Volume 15 was written by Roy with illustrations by Ririnra.

Ryoma has reached the Sea of Trees of Syrus at last. He explores it on his own for a time before running into Glen, a wildly bombastic S-rank adventurer. Together, they decide to head for Korumi Village, which sits deep in the Sea of Trees. The two power their way through the woods, taking out and cooking up high-ranking monsters that stray into their path. What else awaits them in the woods, and what will become of Ryoma's quest for the gods?
