Additionally, characters like Jiraiya, who has influenced Naruto's growth and might be involved in his journey to break the chains, could be among the main characters.
Well, Naruto is surely a main character. Since it's about breaking chains, perhaps characters who represent the 'chains' in some way could also be important.

Obviously Naruto would be one of the main characters since it's in his name. There might also be his usual friends like Sasuke and Sakura.
