Ep. 9: The party seals a sewer gate to stop goblins and confronts Sword Maiden's past trauma.

The group realizes a mirror connects Water Town sewers to the green moon, enabling goblin entry. While Lizard Priest detaches the mirror, the team defeats the Goblin Champion’s counterattack. Goblin Slayer shelters the party beneath the mirror as Dwarf Shaman collapses the roof, crushing all goblins while leaving the group unharmed. They encase the mirror in cement and sink it in the river to prevent future misuse. Goblin Slayer reports to Sword Maiden, who admits a giant alligator is her familiar and that a demon-worshiping cult placed the mirror. She confesses to delaying action to make others understand goblin cruelty. Goblin Slayer states he cannot cure her trauma but will kill goblins if asked, easing her concerns. On the return trip, he announces plans to make ice treats, with the party agreeing to assist.
