The movie begins with Goblin Slayer and his companions, Priestess, High Elf Archer, Dwarf Shaman, and Lizard Priest, taking a well-deserved break after their recent encounters with goblin hordes. However, their respite is short-lived when they receive a new quest that requires their immediate attention. The Sword Maiden, a former adventurer and revered figure, seeks their aid in dealing with a resurgent goblin threat.
The team arrives in a remote village known as Osmanthus, where the Sword Maiden resides. They learn that goblins have managed to infiltrate the village and have taken the Sword Maiden’s childhood friend, Noble Fencer, captive. Furthermore, the goblins have stolen a treasured artifact known as the “Crown of Wisdom,” which grants immense power to its wearer. In a bid to reclaim the stolen artifact and rescue Noble Fencer, Goblin Slayer and his comrades agree to assist the Sword Maiden.
As the team delves deeper into the goblin-infested catacombs beneath Osmanthus, they encounter increasingly dangerous and cunning goblin forces. Goblin Slayer’s strategic prowess and unyielding determination prove invaluable in their battles against the horde. Along the way, each character faces personal challenges and confronts their own fears, leading to significant character growth and development.
The plot thickens when the true intentions of the goblin horde are revealed. Led by a powerful goblin lord, the goblins plan to use the Crown of Wisdom to evolve their species, becoming an even greater threat to the world. Goblin Slayer and his companions find themselves in a race against time to prevent the goblins from achieving their goal and save not only Osmanthus but also the entire realm from destruction.
