One possible plot twist could be that Naruto's braces give him some sort of new power. Maybe they are made from a special chakra - conductive material. So when he uses his ninjutsu, the braces enhance his power output in unexpected ways. For example, his Rasengan could become even more powerful and have new properties like being able to change direction mid - flight. Another plot twist could be that the braces are part of a disguise by an enemy. They are actually a device to spy on Naruto and his friends. But Naruto discovers this and turns the tables on the enemy by using the braces' features against them. Also, it could be that the braces are a gift from a mysterious figure who has a connection to Naruto's past, and they hold the key to unlocking some long - forgotten family secret.
The braces could be cursed. In the Naruto world, curses are common. The curse on the braces could start affecting Naruto's chakra flow in a negative way. But instead of being weakened, Naruto uses this as a chance to learn how to control his chakra in a different way. He might discover that by reversing the flow of chakra through the braces, he can nullify the curse and gain a new ability. Another plot twist could be that the braces are made from a rare metal that is only found in a certain forbidden land. This leads Naruto and his team on an adventure to that land, where they face all kinds of challenges and discover more about the history of the braces and their significance in the ninja world.
One possible plot twist could be that the scythe is actually a cursed weapon. It might start to influence Naruto's mind, making him more aggressive and less like his usual self. This could lead to his friends becoming worried and trying to find a way to break the curse on the scythe.
One possible plot twist could be that they face opposition from the Hidden Leaf Village. Since same - sex relationships might not be as openly accepted in the traditional ninja world. Another twist could be that they have to go on a dangerous mission together right after getting married, which tests their new relationship. And perhaps there's a secret enemy who wants to break them apart because their union represents a new kind of hope in the village.
Well, perhaps a plot twist could be that Naruto gets cursed. This curse makes him forget all about Ino and their relationship. Ino then has to go on a journey to find a way to break the curse. Along the way, she might face many challenges and meet new characters who either help or hinder her. Or maybe there's a twist where it's revealed that Ino was arranged to be married to someone else in her family long ago, and she has to fight against the family traditions to be with Naruto.
A third plot twist could be the appearance of an old enemy from either of their worlds. For instance, if one of Naruto's old foes teams up with an enemy from Esdeath's world. They would then have to put aside their differences and work together to defeat the common enemy, which could either strengthen or strain their marriage.
Perhaps the nin dog is actually an ancient and powerful being that has been sealed in the form of a dog for centuries. Naruto getting it could be part of some prophecy. As Naruto trains with the dog, he unlocks the dog's true form and powers bit by bit. This could involve him having to face some really tough challenges, like ancient curses or powerful enemies that are also interested in the dog's power.
One possible plot twist could be that Naruto has to face a powerful enemy right before the wedding. This enemy might be someone from his past who wants to disrupt his happiness. Another could be that Hana discovers a long - lost relative who has some secrets about her family that could change their relationship. Or perhaps there's a mix - up with the wedding arrangements, like the wrong venue being booked, which leads to a series of comical and heartwarming events as they try to fix it.
A plot twist could be that Ayame is actually part of a prophecy related to Naruto. For example, their marriage is foretold to bring either great prosperity or great disaster to the Hidden Leaf Village. This makes their relationship more than just a love story and puts a lot of pressure on them, as they have to figure out how to fulfill the prophecy in a positive way.
One possible plot twist could be that an old enemy resurfaces just as they are about to get engaged. This enemy might try to disrupt their relationship by spreading false rumors about Naruto, like he has some hidden dark power that could endanger Hinata. Another twist could be that Hinata's family has some ancient clan secret that surfaces and creates a rift between them and Naruto's side. Maybe the secret is related to a power that the Hyuga clan once had and lost, and they fear Naruto might be involved in its re - emergence in a negative way.
One possible plot twist could be that their marriage causes a rift in the ninja world. Some might oppose it due to Itachi's past actions. Another could be that they discover a new power that comes with their union, which is crucial in saving the world from a new threat. And perhaps they have to deal with family issues, like Naruto trying to make Itachi feel welcome in Konoha despite his past.
One possible plot twist could be that right before the wedding, Naruto has to go on a dangerous mission. This could put their relationship to the test as Sakura has to deal with the fear of losing him. She might even consider calling off the wedding. Another plot twist could be that an old enemy resurfaces and tries to use Sakura as a leverage against Naruto, forcing him to make a difficult choice between his love and the safety of the village.
