Maybe in the fanfiction, the Naruto characters end up in the 'Goblin Slayer' world. A female knight takes Naruto under her wing, teaching him about the ways of her world. Meanwhile, Sasuke is intrigued by the dark magic that the goblins possess and is tempted to use it for his own power - seeking goals. The female knight has to convince Sasuke that this path is wrong, all while they fight off hordes of goblins together.
One possible plot could be that the female knight from the 'Goblin Slayer' world gets transported to the 'Naruto' universe. She teams up with Naruto and his friends to fight against a new threat that is a combination of goblins and some of the villains from the 'Naruto' world, like Orochimaru who has somehow managed to use goblin - like creatures in his experiments.
In this crossover, the female knight could be a long - lost relative of one of the ninja clans in the 'Naruto' universe. She brings with her the knowledge of goblin - slaying techniques. The 'Naruto' characters are initially skeptical but soon realize the value of her skills when a group of goblins, empowered by some strange chakra - like energy, start attacking the Hidden Leaf Village. Together, they combine their abilities, with Naruto using his Rasengan in new and creative ways to fight the goblins alongside the female knight.
One possible plot could be that the Guardians from Destiny are called to the world of Goblin Slayer due to some strange energy anomaly. They team up with the Goblin Slayer to fight against an army of goblins that have been enhanced by a Darkness - like power. The Guardians' advanced technology and powers would make for an interesting contrast with the more medieval - style combat of the Goblin Slayer.
One possible plot could be that the Doom Slayer is somehow transported to the world of Goblin Slayer. He then teams up with Goblin Slayer to take on an especially powerful horde of goblins that have been corrupted by demonic forces from Doom. Their combined skills in combat, the Doom Slayer's superhuman strength and arsenal, and Goblin Slayer's knowledge of goblin tactics would make for an epic battle.
In many Goblin Slayer fanfictions, the female knight often represents a symbol of courage. She might be depicted as having unique combat skills, perhaps trained in a different style compared to Goblin Slayer. For example, she could be more versed in swordsmanship with a touch of elegance, while Goblin Slayer is known for his brutal and effective methods. Her character can also bring a different dynamic to the group, adding a bit of a chivalrous aspect to their adventures.
One way the female knight and Goblin Slayer could interact is through mutual respect. Despite their different approaches to combat, they recognize each other's skills. For instance, the female knight might admire Goblin Slayer's single - minded focus on eliminating goblins, while he respects her more traditional knightly values.

Another interesting plot could be a political intrigue - based one. The world of Goblin Slayer has its own political structure.

A Naruto is Goblin Slayer fanfiction could revolve around Naruto's sense of justice in the Goblin Slayer universe. Naruto is known for his strong belief in protecting the weak. In the world of Goblin Slayer, there are many innocent people being terrorized by goblins. So, Naruto could step in and use his powers to make a difference. He might start by rescuing villagers from goblin raids, and as he becomes more well - known, he could inspire the local warriors to be more fearless in the face of goblins. There could also be some interesting interactions between Naruto and the different races in the Goblin Slayer world, such as the elves or dwarves.
For a Goblin Slayer crossover fanfiction, consider a crossover with 'Harry Potter'. The Goblin Slayer could be transported to the wizarding world. He would be confused by the magic there at first, but then realize that goblins also exist in this world. He could team up with Harry and his friends to stop a goblin - related dark magic plot. This would bring a unique mix of the gritty, down - to - earth fighting style of the Goblin Slayer with the magical world of 'Harry Potter'.
How about a crossover with 'Fairy Tail'? The Goblin Slayer's serious and methodical approach to slaying goblins could contrast with the more flamboyant and magic - using mages of Fairy Tail. They could team up to fight goblins that have been magically enhanced or are causing trouble in the Fairy Tail world.

He then uses his advanced weaponry and combat skills to help the Goblin Slayer in his never - ending fight against the goblins.
