Iruka - sensei could be an unexpected ally. He has always been important in Naruto's life. In this fanfiction, he could have some latent sorcerer abilities that he discovers later and uses to support Naruto. His teaching skills could also be applied to help Naruto understand the ways of the sorcerer world better.
Sakura could be one of his allies. Even in a sorcerer - themed fanfiction, her medical skills could be translated into some sort of healing magic within the sorcerer world, and she would always be by Naruto's side.
Naruto's allies could include not only his friends from Konoha but also some unexpected characters. Maybe Gaara, as the Kazekage, would form an alliance with Naruto's empire. Their shared experiences of being outcasts in the past could strengthen their bond. Hinata would also be by his side, offering her gentle support and her Byakugan abilities to help in matters of security and intelligence - gathering within the empire.
Sasuke could be one of his allies. He might be a rival knight at first but then they realize they have to work together. Sakura could be a healer knight, always there to patch up Naruto and the others after battles. Kakashi could be a wise old knight who gives Naruto advice on knightly matters.
Sasuke could potentially be an ally. Even though they have their differences, in the Akatsuki setting, they might realize they need to work together. Another could be Itachi. Itachi has his own motives and might see Naruto as a key to achieving certain goals within the Akatsuki. Also, Konan could be an ally. She seems to be more open - minded compared to some of the other members and might be swayed by Naruto's positive attitude.
Sakura could be one of his allies. She's intelligent and quick to learn, so she might pick up on the basics of alchemy from Naruto and help him in his alchemical endeavors. She could use her medical knowledge along with alchemy to create new healing techniques.
The other members of Team 7 like Sakura and Kakashi could also be his allies. Sakura could use her medical ninjutsu to heal any injuries Naruto and the team get in space battles. Kakashi could offer his wisdom and combat experience, guiding Naruto in this new and unfamiliar space - filled adventure.
Daryl Dixon could also be an ally. Daryl is a great hunter and tracker. Naruto could learn from Daryl's skills in the new environment, and Daryl could be impressed by Naruto's unique abilities. They could form a strong bond while out on scavenging missions or fighting against large groups of walkers.
His usual friends like Sasuke and Sakura could be his allies. They have been through a lot with him and would likely support him in his new role. Also, Kakashi, who has been his mentor, would probably be on his side, guiding him through the political and leadership aspects that come with being heir to the throne.
Definitely, the Akatsuki members who have reformed could be potential allies. They have unique powers and knowledge of the ninja world. Naruto's ability to see the good in people might lead him to recruit some of them. Additionally, the toads from Mount Myoboku could be allies, providing their prophetic knowledge and combat support when needed. And, of course, his old friends from Konoha like Kiba and Choji would come to his aid if the situation called for it.
In this fanfiction, Naruto might also have allies from other villages. Gaara, for example, could form an alliance with Naruto. They both have had their own struggles and understand the importance of power. Gaara's sand abilities would be a great asset to Naruto's mob. And then there's Rock Lee, who might be drawn to Naruto's new - found leadership and see it as a way to test his own strength and loyalty.
Sasuke could be one of his allies. Sasuke's natural combat skills and his sharingan would make him a great asset in aerial battles. He could quickly analyze the enemy's movements and strategies.
