Perhaps in this fanfiction, Naruto's role as a janitor gives him a unique perspective. He might be cleaning the halls of a major mage's stronghold. While doing so, he overhears conversations about an upcoming battle in the Fate world. His ninja skills from his original Naruto world could come in handy in this new situation. He could use his stealth and quick reflexes to avoid getting caught while he tries to figure out how to help or protect the people he's come to care about in this new universe.
Well, one possibility could be that Naruto, as a janitor, stumbles upon some dark secrets in the Fate universe while cleaning up. Maybe he discovers a hidden room with a powerful and dangerous magical artifact that's crucial to the overarching plot of the Fate world. And his simple janitor life gets turned upside down as he becomes a target for various factions who either want to use him to get to the artifact or silence him.
At first, Naruto might be a bit downcast about being a janitor. But as he experiences the unique aspects of the Fate world, he'd start to grow. He'd learn about magic and the complex relationships between characters. His natural determination would make him strive to improve his situation, not just as a janitor but also in the grand scheme of the Fate world.
The plot could be that the janitor, who is gay, is trying to find his place in a new city where he just got a job. He meets another gay man at a local coffee shop near the building he cleans. They start to hang out and become friends. But the janitor has some family issues back home because of his sexuality. His new friend helps him deal with those issues, and in the process, their friendship turns into love. They then have to face the challenges of society's views together.
Well, the plot could involve a gamer being suddenly transported into the Fate universe. Maybe they use their gaming knowledge to quickly adapt and form alliances with various Servants. They could try to outwit the other Masters in the Holy Grail War by using unique strategies inspired by games.
One possible plot could be that Naruto, in this fanfic's universe, has some sort of connection to the concept of 'Father of Asia' within the Fate world. Maybe he is a reincarnation of an ancient Asian hero who had the title. He could be brought into the Fate conflict, using his ninja skills and his strong will to fight against the other Servants. His rasengan and shadow clone jutsu might be modified to fit the more magical and complex rules of the Fate universe.
One possible plot could be Naruto ruling over a united ninja world. He would focus on eliminating old rivalries and promoting trade and cultural exchange between the villages.
Maybe in the fanfiction, Naruto is in a game where the rules are based on different ninja clans' techniques. So he has to learn and adapt to new ways of using his chakra and jutsu. He could start as a low - level character in the game and level up by defeating bosses that are actually replicas of powerful shinobi from the Naruto universe. This would give him the opportunity to explore different aspects of his own powers as well.
Yes, there are likely some Fate fanfictions out there where Naruto is depicted as a servant. The concept of crossing over Naruto with the Fate universe allows for interesting combinations. Writers might explore how Naruto's unique abilities, like his shadow clones or Rasengan, would function within the framework of the Holy Grail War and the servant system in Fate.
You could try looking on fanfiction websites such as Archive of Our Own (AO3) or FanFiction.net. These platforms have a large collection of fanfictions and there's a good chance you'll find it there.
I'm not sure specifically as I haven't read it. But generally, a Naruto x RWBY fanfiction might involve characters from Naruto and RWBY universes in a story where one of the main characters is a janitor. It could be about how this janitor character gets involved in the adventures or events that are typical in both Naruto and RWBY worlds.
Well, it could start with Naruto accidentally coming across something related to Reddick. Maybe he sees a symbol or hears a story about Reddick and becomes intrigued. Then he starts to study more about Reddick in his free time. This new interest could influence his decision - making in battles. For example, he might use some of Reddick's supposed strategies in combat. His friends would be confused at first but gradually accept his new passion.
