One possible plot could be that Naruto, while on a mission in a strange dimension, meets Erza. They initially clash due to their different ways of handling things but gradually fall in love. Naruto then decides to stay in Erza's world and they get married, facing challenges from both their friends and enemies who are skeptical of their union.
A plot could start with Erza visiting Naruto's world through some magical portal. At first, Naruto is intrigued by this strong - willed and powerful woman. They start training together and learn from each other's combat styles. As they spend more time together, feelings develop. Eventually, they decide to get married. But there are those in both worlds who oppose it. So they have to prove that their love can bridge the gap between their two very different cultures and power systems.
Maybe Naruto is accidentally transported to the Fairy Tail world. He and Erza team up for a big quest. During this time, they discover their shared values of loyalty and protecting their friends. This bond deepens into love, and after some trials like defeating a powerful dark mage together, they get married. Their marriage then unites the ninja and mage worlds in some ways, like sharing techniques and knowledge.
Perhaps there is a prophecy that only Naruto and Erza together can fulfill. They start off as strangers but as they journey to fulfill the prophecy, they discover that they have a lot in common. They both have a strong sense of justice and a will to protect their friends. As they face numerous enemies and obstacles, their friendship turns into a deep respect for each other's abilities, and they become a formidable team.
In this fanfiction, perhaps Erza is found by Naruto when she's injured. Naruto takes her back to Konoha. Since he has a big heart, he wants to give her a home. As she recovers, they start to bond. Erza might be amazed by the chakra system and Naruto could be intrigued by her magic. They could then go on adventures together, with Naruto protecting her like a father figure at first, and later they become equal partners.
One possible plot could be that Naruto somehow gets transported to the Fairy Tail world before Erza is born. He then meets Erza's mother and gets involved in her life. Eventually, he becomes a father figure to Erza as she grows up, teaching her some of his ninja skills and values from the Naruto universe.
Maybe Naruto is on a mission to a place that has some connection to Erza's world. They meet by accident and at first, they don't get along because of their different ways. But as they learn more about each other's pasts and struggles, they start to respect and like each other. Eventually, during a festival in a village they are passing through, they get caught up in the moment and kiss.
Well, one possibility could be that Naruto, with his strong sense of justice and his own experiences of growing up alone, takes Erza under his wing. He might teach her some of his ninja skills, like how to move stealthily or use chakra in a new way. And Erza, being the strong - willed character she is, would adapt these skills into her own fighting style.
In this fanfiction, perhaps Naruto discovers his connection to Erza later in life. It could start a whole journey of self - discovery for him. He might travel to different dimensions or meet characters from Erza's world. This could lead to new alliances and conflicts. He may also learn new magic - like abilities that he combines with his ninja chakra, creating a whole new form of combat that no one has seen before in the Naruto universe.
Maybe in this fanfiction, there are some artifacts or powers that both Naruto and Erza are after. Erza betrays Naruto to get her hands on this power first. This could set off a chain of events where Naruto has to find a way to stop her from misusing the power. It could also make Naruto question his own judgment in trusting her in the first place.
Perhaps in this fanfiction, Naruto returns to Erza because there is a prophecy that only he can fulfill in her world. He might bring new hope to the people there. He could also learn some new fighting techniques from Erza and her comrades while sharing his own ninja knowledge. This would lead to an interesting exchange of cultures and fighting styles.
Yes, it can be quite popular in certain fanfiction communities. Combining characters from different anime universes like Naruto and Fairy Tail (where Erza is from) allows for unique and creative storylines. Fans enjoy exploring how the personalities and powers of these two characters interact in a romantic relationship.
One possible plot could be that Naruto and Fuu meet during a mission. Fuu is initially intrigued by Naruto's determination. As they spend more time together, they discover they share a similar sense of humor. Eventually, Naruto realizes his feelings for Fuu are more than just friendship and he proposes. Their wedding would be a grand affair, with all of Naruto's friends from Konoha attending.
