With all those adventurers fighting together and following the Slayer’s plan, the goblin army is dispatched all too easily. Just when a goblin thinks he has the upper hand with a surprise attack, he’s met by a mailed fist, arrow, or blade. Meanwhile, Goblin Slayer himself informs the Goblin “Lord” that the home he’s trying to flee to is already gone.
That being said, the Slayer is not used to one-on-one combat out in the open, and the Lord, while cowardly, is still huge, and proceeds to stomp all over the Slayer’s head. Fortunately, the Priestess arrives, casting dual protection spell planes that immobilize and crush the lord. Slayer finishes him off, and is then healed by the Priestess, who didn’t use all three of her spells for protection.
The Priestess is cross that he pushed himself too hard once more, as she learns he was only bait, and trusted her to bail him out once the lord thought he would be victorious. When the sun rises, the Slayer needs help getting back home, but the adventurers, his party members, and Cow Girl are all elated to see him in one piece.
At the guild celebration, Goblin Slayer buys everyone a drink, as he promised. The Priestess asks if she can get an extra reward: if he’ll remove his helmet for her. He does, and it causes a right commotion in the guild, many of the members of which had a placed bids on who or what would be underneath.
But more than fascinated with his face, the Priestess, the rest of his party, the other adventurers, all share one thing in common: they now consider Goblin Slayer a friend and ally, and coming to his aid isn’t a matter of luck, but obligation. They do it gladly, because if it weren’t for him they might not have a town.
Thus ends Goblin Slayer’s saga…but only for now. A post-credits announcement promises his return. He intends to start on the path of an adventurer, but I assume that doesn’t preclude him from slaying goblins; it just means he’ll be going to more far-flung places to do it. And he won’t be doing it alone.
