One possible plot development could be the initial shock and adjustment for both Naruto and Mei. They would have to deal with the reactions of their respective villages. Naruto's friends in Konoha might be surprised, and Mei's allies in Kirigakure would also have their thoughts.
I'm not sure of specific 'naruto is engaged to mei fanfic' stories off - hand. But you can try searching on fanfic platforms like Fanfiction.net or Archive of Our Own. There are likely to be many Naruto - related fanfics there, and with some searching, you might find the ones about Naruto being engaged to Mei.
Well, a plot twist could be that Mei is actually engaged to Naruto as part of a long - term plan to steal some secret from Konoha. But as she spends time with Naruto, she starts to really fall in love with him. This creates an internal conflict for her as she has to choose between her village's mission and her new - found love. Or perhaps Naruto discovers some dark secret about Mei's past that makes him question their relationship, but then he realizes that people can change and that he still loves her regardless.
Well, it's possible. Fanfic writers have very creative minds. They might think it would be interesting to pair Naruto, a ninja from the Hidden Leaf Village, with Rias, a devil from the High School DxD universe. However, not all fanfics are easy to find. You may need to dig deep into the fanfic archives, using specific tags related to both Naruto and Rias on the fanfic platforms.
Well, it could have a huge impact. First of all, the other villages might see it as a sign of a new power bloc forming. This could either make them feel threatened and start to form their own alliances, or they might try to get on the good side of Konoha and Kirigakure. In terms of the ninja world's culture, it could start to change the way inter - village relationships are viewed. Love between ninjas from different villages might become more acceptable. Also, their combined influence could lead to more diplomatic solutions to conflicts rather than just fighting.
One common theme is the clash of cultures. Naruto is from Konoha and Sona is from a different place. Their engagement often brings up issues related to different traditions and values.
It could be really exciting. Imagine Naruto's ninja skills and Rias's devil powers working together. Maybe they meet in some sort of interdimensional rift. Naruto might be confused at first by Rias's world, but his determination would help him adapt. And Rias would be intrigued by Naruto's strength and positive attitude.
If Naruto and Sakura were engaged in a fanfic, their future could be full of adventure and love. They might go on missions together, with Naruto's strength and Sakura's medical skills complementing each other. Their relationship could also bring new dynamics to the Hidden Leaf Village, inspiring the younger generation. And of course, they would have a beautiful wedding surrounded by their friends and family.
One good 'naruto is engaged to sona fanfic' might be 'Naruto and Sona's Unexpected Bond' which explores how their relationship develops from the engagement. It shows Naruto's initial confusion and how Sona tries to make him understand the significance of their union.
When Naruto and Sakura are engaged in a fanfic, their relationship would change the village significantly. Their strong bond would give hope to those who have lost loved ones in the past. It could also lead to a more inclusive environment in the village, where everyone feels welcome regardless of their abilities. Moreover, they could start initiatives to improve the living conditions in the village, using their influence and resources. Their relationship would be like a beacon of hope and progress for the Hidden Leaf.
