Goblin Slayer (Japanese: ゴブリンスレイヤー, Hepburn: Goburin Sureiyā) is a Japanese dark fantasy light novel series written by Kumo Kagyu and illustrated by Noboru Kannatsuki. A manga adaptation by Kōsuke Kurose is serialized in the Monthly Big Gangan magazine, and a second adaptation by Masahiro Ikeno runs in the same magazine. A prequel manga by Kento Eida runs in Young Gangan. Both the novels and the manga adaptations have been licensed by North American publisher Yen Press.
Despite being a silver-ranked adventurer, Goblin Slayer’s choice of equipment poorly reflects his rank. He is often seen equipped in grubby leather armor with chain mail underneath paired with his signature cheap-looking helmet (which originally had horns) that envelops his head entirely in protective metal. However, due to the excellent sense of smell goblins possess, Goblin Slayer has a habit of neglecting the cleanliness of his armor as clean equipment would reek of metal, which would immediately alert goblins.
In contrast, Goblin Slayer’s appearance is often mocked and ridiculed by most whom fail to see the practicality and effective functionality behind it. Moreover, the grimy appearance combined with his down-grade equipment has, on more than one occasion, caused people to mistake him for an undead.
Goblin Slayer usually carries a cheap and disposable sword of a short length hanging on his left hip in a makeshift scabbard, allowing him to sheath swords of any shape he salvages. Affixed to his left arm is a small round targe, its rim well maintained to be used as a backup cutting weapon.
