I'm sorry I don't know the exact main characters as I haven't read the novel. But usually, there would be the real daughter herself. There might also be her family members, like her parents who may be deceived by the false daughter.

The main characters could include the Star Emperor's closest friends from his youth who now hold important positions in his empire.

Well, in such a light novel, the main character is obviously the one with the goal of becoming the magic emperor.

And don't forget about potential love interests, who can influence the main character's decisions and actions in the story.
The main character is, of course, the Eternal Emperor himself. He is a central figure around which the whole story revolves. He has some unique abilities and a strong will.

Another important character is the antagonist, a powerful being who constantly tries to oppose the Eternal Emperor's plans and rule.
Obviously, the daughter is one of the main characters as she is the final boss. There may also be a father or mother figure who plays an important role in the story, perhaps trying to understand or deal with their daughter's situation.
