The main characters are surely Naruto and Ichigo. But don't forget about Kakashi from Naruto. He could be a mentor figure in this new reincarnation story, guiding Naruto (and maybe Ichigo too in some ways) with his wisdom. On the Bleach side, Uryu could be there. He has his own unique abilities and his relationship with Ichigo was complex. In this fanfiction, he might be a rival or an ally to the reincarnated Naruto - Ichigo. Also, Sakura from Naruto might be involved, perhaps with some new skills or a different role due to the reincarnation concept.
Obviously, Naruto and Ichigo would be the main characters. Since it's a reincarnation fanfiction, they would be at the center of the story. But other characters from both universes could also be important. In the Naruto side, Sasuke might play a role as he has a strong connection with Naruto. From the Bleach side, Rukia could be involved as she was the one who turned Ichigo into a Soul Reaper. Their interactions with Naruto and Ichigo in this new reincarnation scenario would add depth to the story.
