If Naruto reincarnates as Issei, the plot could be really exciting. Naruto's reincarnation would bring his own set of values and skills. He would first have to deal with the fact that he's in a different body and a different world with different rules. He might initially struggle with the perverted nature of Issei's character, but gradually change it to be more in line with his own values. In battles, he would use his Naruto - like combat abilities, such as shadow clones and rasengan. He could also use his experience in making friends and allies in Konoha to form stronger relationships in the High School DxD world. This could lead to new alliances between devils, angels, and other factions, completely changing the way the story unfolds.
The plot might start with Naruto being confused about his new identity as Issei. But soon, he'd start to use his chakra and ninjutsu to gain an edge. He could also change the relationships Issei has. For instance, he might approach the devils with more caution and suspicion due to his ninja upbringing. As the story progresses, he could introduce new combat styles and strategies, shaking up the power balance in the world of High School DxD. And he might also try to find a way to bring some of the values he held dear in the Naruto world, like loyalty and perseverance, to this new world.
The plot could involve Naruto having to adapt to Issei's world of devils, angels, and fallen angels. He'd likely use his ninja skills to stand out. Maybe he'd try to form a different kind of peerage, using his knowledge of teamwork from Konoha.
Well, it would be really interesting. Naruto's skills and values would be transferred into Issei's world. He might bring his ninja way to deal with the supernatural threats in Issei's universe. Maybe he would use his shadow clone jutsu to confuse the devils and fallen angels, and his rasengan could be a powerful weapon against them.
His combat abilities would change a lot. Naruto's ninjutsu like the substitution jutsu could be used in new and interesting ways in Issei's world. His ability to sense chakra might be transformed into something that can detect the different types of energy in Issei's universe, such as the demonic energy or the holy energy.
Well, if Naruto reincarnates in RWBY fanfiction, he could change the power balance in Remnant. His ability to use Rasengan and other powerful jutsus would make him a formidable force. He may also form unique bonds with the characters in RWBY. Maybe he would team up with Ruby and help her improve her scythe - fighting skills with his own melee combat experience.
It would mean a really interesting mash - up of two different fictional worlds. Issei might gain unique abilities and a different perspective on combat and self - improvement.
Well, one possible plot could be that Naruto discovers some ancient and powerful jutsu that allows him to reach across different dimensions or realms to revive Issei. Maybe Naruto is on a mission to save the world from a new threat and he realizes that Issei has some unique power or knowledge that can help. So he uses this jutsu, brings Issei back, and then they team up to face the common enemy.
Issei might inherit Naruto's chakra. This would give him the ability to perform ninja techniques like the Shadow Clone Jutsu. He could create multiple clones of himself to confuse enemies or help with tasks. Also, he could potentially inherit Naruto's ability to sense negative emotions, which would be useful in detecting threats.
One possible plot could be that Issei is in a new world or situation where he's in danger. Naruto, with his skills and determination, steps in to protect him. Maybe Issei has some kind of special power or knowledge that certain villains want, and Naruto uses his jutsu like the Shadow Clone Jutsu to fend off the attackers and keep Issei safe.
Well, Naruto is a very emotional person, wearing his heart on his sleeve. Issei could be more calculating in some ways. Naruto's emotional outbursts might seem strange to Issei at first, but he would soon realize that it's part of Naruto's charm. Issei's more thought - out approach could also be something Naruto would learn from. When it comes to protecting Issei, Naruto's impulsive nature might cause some issues, but Issei would be there to reel him in a bit, creating an interesting dynamic between the two characters.
It would likely have a huge impact on the plot. New alliances might form around protecting the baby. Enemies could see the baby as a threat or a valuable asset. The story could shift from their individual adventures to more family - focused ones.
Well, it would be really interesting. Naruto has his own set of values like perseverance and friendship. If he were Issei's father, he might instill those values in Issei. Maybe Issei would grow up with a different kind of power, not just the Sacred Gear from his original story but also some ninja techniques from Naruto. And Naruto would probably be very protective of Issei, teaching him how to fight and face challenges in a more ninja - like way.
