Goblin Slayer, Vol. 9 (light novel)

Goblin Slayer has temporarily separated from his party for what is supposed to be a routine delivery job with Cow Girl. However, things take an unexpected turn when they're ambushed by a horde of goblins under the command of a mysterious, ghastly creature. It's up to Goblin Slayer both to protect his childhood friend and fight off the foes all on his own, as the rest of his party is elsewhere-Priestess and the others have ventured to the snowy northern mountains, a region locked in a perpetual winter under the control of the evil Ice Witch... Can Priestess successfully lead the party to victory in Goblin Slayer's stead?
