Yes, in many fanfictions, Naruto is often depicted as a huge fan of the Fourth Hokage. After all, the Fourth Hokage is his father. Naruto grows up idolizing the Fourth Hokage's heroic deeds and wishes to be like him.
Another scenario could be during battles. Naruto might be inspired by the Fourth Hokage's battle strategies. He may think to himself, 'What would the Fourth Hokage do in this situation?' and then try to act accordingly. In some fanfictions, Naruto even visualizes the Fourth Hokage beside him, giving him advice during tough battles.
Naruto himself could be a likely candidate. Given his strength, leadership skills, and his dream of uniting the ninja world, he would make a great 6th Hokage.
I don't know who Sir Roger is. If you can provide more background information about Sir Deqing Luo, I will try my best to answer for you.
The original work was equally exciting. You could click on the original work of " The Story of Rose " to understand the plot in advance!
I'm not sure. It's possible that 'Sir' is inspired by real-life incidents, but it might also be pure imagination. The way it's presented and the details within might give clues, but without further info, it's tough to tell.
