Naruto's role in the 'naruto revives issei fanfiction' is that of a savior. He uses his abilities, be it his chakra control or some special jutsu, to bring Issei back. He is also the one who will probably train Issei in the ways of the ninja world if needed. Issei is the revived character. His role is to adapt to this new world he has been brought into. He might have his own set of powers from his original world that could be useful in the battles they will face. He is also there to form a bond with Naruto and together they become a formidable team against their enemies.
Obviously Naruto is one of the main characters as he is the one being revived. And Kami, who is performing the revival, is also a crucial character. There might also be other characters like Sasuke, Sakura, and Kakashi who could be involved in the story after Naruto's revival. For example, Sasuke might be initially skeptical about Naruto's return or Sakura could be overjoyed and help Naruto get back to his normal self.
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.
It could be a new and powerful enemy that the past Hokages once sealed away. With Naruto's revival of the Hokages, this enemy somehow gets released or starts to break free from its prison. This antagonist would be extremely powerful, having been a threat that required the combined efforts of the Hokages to deal with in the past.
In this fanfiction, Itachi is the catalyst for change in Naruto's life. He's the one who provides a new family structure for Naruto.

She may look to Itachi for advice on how to better understand Naruto and how to strengthen their relationship, while also dealing with her own insecurities and the new family dynamic.
Well, Naruto would be the one to bring hope and his unique brand of optimism to the past. He could show the younger versions of characters how to be a better ninja. Sasuke, being the brooding and intelligent one, would analyze the situation of the past and figure out how to use their time - traveling advantage to the fullest. Sakura, she'd be a key player in both the medical and combat aspects. She could teach the past medics new techniques. And Kakashi, he's the experienced one. He'd be making sure the team doesn't make any rash decisions that could mess up the timeline further.
Rias could be a main character. She has a strong connection with Issei and in a fanfiction about him as the Prince of Darkness, she might play a role in helping him control his new power or deal with the political ramifications of his new status.
The main characters are Naruto and Hanabi. Naruto, being the hero type, is likely to be the protector. He is strong and has a big heart, so he would try to rescue Hanabi from her situation of abuse.

She may be portrayed as an antagonist or at least someone who has to deal with Naruto's godlike presence.
Issei for sure. And there might be a rival character who has wronged Issei in some way, which prompts the need for revenge.
