Well, one possibility could be that Naruto, with his leadership skills from being a ninja, forms a guild for different purposes. Maybe it's a guild for protecting the village in a different way, like taking on non - ninja related threats. He could gather people with unique skills, like some with great knowledge of herbs for healing, others with skills in building and construction to fortify the village. And they all work together under Naruto's guidance, just like how he led his ninja teams before.
It could be that Naruto makes a guild to explore the outside world. He's always been curious about what's beyond the village.

Along the way, they face challenges that require both Naruto's combat skills and the unique abilities of the other guild members. The guild becomes a symbol of exploration and discovery in the Naruto universe.
The guild could be a place for ninjas from different villages to come together. Naruto, believing in unity among all ninjas, creates a guild that accepts members regardless of their village origin. This would cause some initial friction as old rivalries and suspicions surface. But Naruto, with his charisma and determination, would work towards building trust among the members. The guild's main goal could be to fight against a new, greater threat that endangers all the ninja villages, and they would need to put aside their differences to succeed.
In this fanfiction, Naruto could build a guild to train the next generation of ninjas in a new way. He realizes that the traditional village - based training has some limitations.

The guild might also attract some former villains who want to reform and contribute to a new ninja society.
The plot could involve Naruto being an outcast in the ninja world after some false accusations. The dark guild offers him a place where he feels accepted. However, the guild's activities are against the values he once held.

It could also lead to some interesting battles where Naruto uses his unique skills against his former comrades who now see him as a threat.
The plot could revolve around a new Dark Guild that is formed specifically to take over both the Naruto and Fairy Tail universes. They start by stealing important artifacts from both worlds. Naruto and a team of Fairy Tail's strongest mages are brought together by a mysterious force to stop this new threat. As they investigate the Dark Guild, they discover that the guild's leader has a personal vendetta against both Naruto and Fairy Tail. This vendetta drives his actions and makes him a formidable foe. In the end, through teamwork, strategy, and the unique powers of both Naruto and Fairy Tail, they are able to defeat the Dark Guild and restore peace to both universes.
One possible plot could be that Naruto discovers an ancient and forgotten summoning contract. He decides to make it his own, not knowing what kind of creatures it will summon. As he signs the contract, he is immediately transported to a strange and mysterious realm. There, he meets the initial summon, which is a powerful and intelligent being. This being tests Naruto's worthiness and eventually agrees to help him in his battles against new and dangerous foes in the Ninja world. This new summoning gives Naruto an edge in combat and also helps him gain more knowledge about the hidden secrets of the Ninja world.
One possible interesting plot could be Naruto, as the guild master, having to deal with a powerful dark guild that is threatening the safety of Fairy Tail. He could use his ninja skills and leadership to gather the members and come up with a unique battle strategy.
Well, one possibility could be that Natsu leaves the guild because of a personal mission. Maybe he discovers a dark secret about his past that he believes can only be solved alone, so he leaves Fairy Tail to find out the truth without putting his friends in danger.
Well, perhaps Naruto discovers a strange new power that is related to the keyblade. He could be on a mission and stumble upon an ancient artifact that somehow transforms into a keyblade. Then he has to learn how to use it while still relying on his ninja skills. Maybe he uses it to fight against a new, powerful enemy that is immune to normal ninja attacks.
Maybe Naruto discovers an old sake - making recipe in his travels and decides to try it out. He could face challenges like getting the right ingredients in the ninja world or dealing with people who oppose this new 'hobby' of his.

This, of course, angers the creators of the Fluctlight system who see Naruto as a threat to their control. So, Naruto has to fight against them while also trying to find a way to bring the freed Fluctlight beings back to his world safely.
