Goblin Slayer Brand New Day Manga Chapter 1
He and Apprentice Cleric are in the sewers of East Guild Town clearing out the giant rats and Giant Cockroaches that have infested them. Rookie Warrior manages to kill a giant rat when Appearance Cleric stumbles upon the remains of another Female Porcelain ranked adventurer. She collects the corpse's tag to bring back to the guild. Rookie Warrior's sword is stuck in the dead rat when another Giant Rat attacks, but Apprentice Cleric manages to kill it with Holy Smite. Thinking they are clear, Rookie Warrior tries to get his sword again only for them both to come under attack by Giant Cockroaches. This forces them to retreat out of the sewers leaving his sword behind. The following day, after eating a small breakfast, they think about asking someone for a loaner weapon so they can retrieve his sword. Spearman comes by and says it's a bad idea, however Witch gives them a Magic Candle that could help them find his sword, which would get hotter the closer they would get to it. They meet with Guild Girl for advice, who tells them about using a torch, but suggests them to go ask Goblin Slayer for additional guidance. Reluctantly, they go over to Goblin Slayer and Priestess and after noticing he has a club and not a sword, and ask him why he's carrying it around. Goblin Slayer tells them it has its advantages over a sword because it won't chip or break under normal circumstance. Getting their courage back together, they use what little money they have left to buy a club before heading to the sewers to go and fetch Rookie Warrior's sword. After lighting the Magic Candle, they immediately encounter two giant rats, one of which Rookie Warrior clubs to death; both are surprised by how effective the club really is. Heading westward, the Candle suddenly gets very hot and a Super Giant Cockroach approaches them. They run away but soon deduce that his sword is inside the super giant cockroach. Realizing there was no escape, they turn to fight it. Rookie Warrior gets an idea and grabs the lantern off of Apprentice Cleric's belt and then slams it on the floor, causing a massive fireball to erupt in front of them. The Super Giant Cockroach stops to avoid the fireball and takes flight. After snapping Apprentice Cleric back to reality, Rookie Warrior tells her to use her power. She promptly uses Holy Smite to wound the super giant cockroach, allowing Rookie Warrior to bludgeon it to death. He then uses his dagger to cut open the super giant cockroach to retrieve his sword. That evening, after throwing their clothes they were wearing into the wash, and putting on new ones, they reflect on the day's adventure and realize they have a long way to go.
