Onward to Adventure Goblin Slayer is joined by Priestess and other adventurers who determine a shaman is leading the goblins tunneling to the surface. Due to his size, Heavy Warrior stays to protect the children while everyone else enters the tunnels. Priestess volunteers to lead the trainees to attack the goblins hunting the other trainee group. Goblin Slayer’s group kill the shaman underground. Priestess reaches the other trainees, several dead already, and organizes a safe escape. Wizard Boy hesitates from fear but after recalling a lesson from Dwarf Shaman, he uses a spell to deafen the goblins, knowing his immediate goal is to protect the trainees, not kill goblins. Goblin Slayer's team flood the tunnels from a lake, collapsing it on the main nest. Afterwards, Priestess is promoted to Steel Rank. Wizard Boy, having gotten over his bad attitude, admits goblin killing isn’t for him and plans to start adventuring, learn new spells and slay a dragon. He is flustered that Rhea Fighter insists on teaming up with him, amusing Goblin Slayer so much he actually laughs and advises them to visit his old Rhea friend, Burglar. Cow Girl is delighted Goblin Slayer is happier, but scolds him for completely draining the lake they swam in as children.
