After finding out that Goblin Slayer has been spending so much time with Arc Mage, Cow Girl finds herself becoming shy and awkward in her interactions with him once again. Meanwhile, Spearman and Witch party up for the first time, thanks to Guild Girl's introduction, and set out to take down a warlock-only to find an even deadlier creature waiting for them! Finally, Goblin Slayer and Arc Mage make their way to a dark tower at the very edge of the world...that has become an enormous goblin den?!! From afar, the clacks of rolling dice sound out...

"I think she went far away. And I doubt she will ever come back. But I do not believe she is dead." Now that Goblin Slayer and Arc Mage have parted ways, a whole new story begins! "Is he capable of anything other than hunting goblins?" When a certain promising adventurer's peculiar quest record comes under scrutiny, an Adventurers Guild examiner comes from the capital to the frontier to get a look at the man in the flesh. Thus begins Goblin Slayer's promotion exam under the watchful eye of this senior colleague of Guild Girl...!

Goblin Slayer and his examiner infiltrate the goblin lord's lair and attempt to save a girl being held hostage there—but Goblin Slayer takes a nasty hit to the head in the process...!! Will the two of them be able to make it out, or will his promotion exam end in something far worse than failure?! Meanwhile, having stumbled into a legendary sunken city, Young Warrior’s party comes across a grotesque ritual intended to resurrect the demon lord...!!

Three days after his sister's death, he finally regained the will to move. In the aftermath of a goblin raid, a lone boy mourns the loss of his village, his family... Five years later, that same boy visits a city on the frontier and becomes an adventurer. Despite being the lowest rank and wholly inexperienced, the young adventurer immediately accepts a quest and sets out alone to raid a goblin lair. His mind already burning with a clear vision of his calling, the legend of Goblin Slayer begins!

The novice warrior, who took part in the subjugation attack against Rock Eater, throws himself in the midst of rigorous fighting to honor his fallen comrades. Meanwhile, a young boy single-handedly fights to protect a small village from the threat of goblins. But while felling goblin after goblin in the pouring rain, he's faced with a danger that comes crashing in with the thunder and lightning...

Goblin Slayer's promotion exam begins in earnest! The seemingly simple quest he chose ends up taking him and his examiner all the way to a distant village next to a massive goblin nest. The two of them venture into the nest to exterminate the goblins, where they soon discover that this horde is being led by a kind of goblin more dangerous than any Goblin Slayer has seen before... Meanwhile, after Heavy Warrior collapses due to overwork, Young Warrior's party is sent to investigate the source of the recent frequent, disruptive earthquakes in his place, but the answer they find is something they never could have imagined...!!

In the course of learning his "craft," Goblin Slayer begins building a bit of a reputation for himself...but Goblin Slayer isn't the only one who has to find his place in the world. Cow Girl has her own questions about her role...

When Goblin Slayer and Arc Mage continue their goblin research with a dissection of one they killed in the ruins, they discover something new about the creatures. Rookie Warrior also heads into an abandoned mine with a party of inexperienced but fearless adventurers, attempting to master his weakness, but what will he do when they come under attack from yet another new threat?!

After protecting a village from a horde of goblins, a certain young man has been called "Goblin Slayer" for the first time. One day, while slaughtering yet another group of goblins, he finds a ring that glows with a mysterious light, which he has appraised by an eccentric magician who lives outside town known as Arc Mage. She, in turn, requests his help in compiling a bestiary for the Guild. He is put in charge of the section on-of course, goblins. With a single ring, and a single light, a brand-new story begins.
