Since I haven't read the 'ladies man novel', I don't know exactly. But it's likely that there is a central male character who is the 'ladies man' himself.
In the 'ladies man novel', there is probably the main male character who is good at charming women. There may also be several female characters who are attracted to him or play important roles in his life, like a childhood friend who has always had feelings for him or a sophisticated woman who challenges his usual ways.
I'm not sure specifically as I haven't read the novel in detail, but surely the 'ladies man' himself is a main character.
Sakura, who has a long - standing relationship with Naruto in the original story, would probably be a key female character. Hinata, too, as she has deep feelings for Naruto. There might also be other female ninjas like Ino or Temari who could be part of the story to show Naruto's charm towards different types of women.
There could be an original female character created specifically for this fanfiction. Maybe a new transfer student from another magical school who is immediately drawn to Harry's charm and becomes an important part of his ladies - man adventures.
Sakura is often a main female character in such fanfictions. She might be portrayed as having a different relationship with Naruto, who is the ladies man in this case. Maybe she's initially jealous of all the female attention he gets but then realizes her true feelings for him.
Sam is also important. She's Danny's friend and in some fanfictions, she might react in different ways to Danny's new 'Ladies Man' status. Maybe she's jealous or tries to help him manage this new side of himself.
Without knowing the exact novel, it's impossible to name the main characters precisely. However, if it's a novel centered around 'ladies first', it's likely to have female characters like a young, independent woman trying to make her mark in a male - dominated world, or an older woman with a wealth of wisdom and experience who guides the younger ones.
I don't know for sure as I haven't read the novel. But it could be a group of female friends, like a young woman named Sarah who is the life of the party, and her more reserved friend Emily.
I'm not sure exactly without reading it, but probably the ladies in black are the main characters.
I don't know as I haven't read it. Maybe the first ladies themselves are the main characters.
I'm not sure exactly who the main characters are without reading it, but likely they are the ladies in the choir.
