Goblin Slayer started as a dark fantasy light novel that was turned into 2 different manga series, an audio drama, as well as an animated series. The main character is Orcbolg, known as Beard-cutter as well.
The story revolves around the war between humans and various kinds of monsters that has been happening for a long time now. There's a guild that accepts adventurers. These people accept quests that involve fighting monsters for rewards. The rewards vary but include being part of the rank system. The most successful adventurers have the highest ranks.
The weakest monsters are believed to be the goblins, as such the rewards for fighting and defeating them are the lowest as well. Goblins are usually found alone, and they lack intelligence, fighting strategies, and skills. Some of the goblins are more advanced from all the mentioned points of view and they like to gang together, making them much harder to destroy.
