Since it's a Naruto - related fanfiction, Naruto is bound to be a central figure. However, the story might also focus on some original characters created for this particular fanfic. These could be characters who are part of the shogunate court, such as samurai who serve under Naruto or members of the nobility who interact with him. And don't forget his ninja comrades from Konoha. They may come to visit Naruto in his new role, and their relationships and interactions could be an important part of the story.
It could be about Naruto in a setting where he is a shogun and experiences sorrow. Maybe it's a story that combines the Naruto universe with elements of Japanese shogunate era, and the sorrow could come from various sources like losing friends, facing difficult decisions, or dealing with the power struggles within the new role.
Obviously Naruto is one of the main characters since it's in the title. There might also be other Naruto -verse characters like Sasuke or Sakura who could be part of Naruto's entourage or have their own roles in this Western - inspired setting. And perhaps there are new characters created specifically for this fanfiction, like local lords or samurai who interact with Naruto.
Well, 'Harry Potter Shogun of Sorrow Fanfiction' could be a really creative take on the Harry Potter series. It could involve a plot where a character, perhaps Harry himself, is faced with a new and strange situation inspired by the idea of a shogun. A shogun is a military dictator in Japanese history. So it might be that in this fanfiction, there are aspects of Japanese culture or power dynamics merged with the magic of Harry Potter. The 'sorrow' part could imply that there are some sad or difficult events that unfold due to this new combination of elements.
There could be a young and ambitious samurai as one of the main characters in the 'shogun story'. He might be on a quest to prove himself in the eyes of the shogun. And there could be an old and wise advisor to the shogun who plays a crucial role in the story, guiding the shogun's decisions and actions. Also, a mysterious stranger who enters the shogun's territory and disrupts the existing order could be another main character.
One of the main characters is likely to be a powerful shogun or a daimyo. They are at the center of the political and military power.
Lady Mariko is also a significant character. She is caught between two cultures, being Japanese but having to interact closely with Blackthorne. She is intelligent and plays a crucial role in many of the power plays and cultural exchanges that occur. And there's also Yabu, a daimyo who is involved in the political and military struggles in the story.
In the 'shogun novel', main characters often include the shogun himself, who wields great power and influence. There may be a foreigner, perhaps a trader or an adventurer, who gets caught up in the complex web of Japanese politics. And of course, there will be samurai characters, some of whom are key players in the power struggles and battles that take place in the story.
Again, without more details about the 'shogun original story', it's hard to say. But likely there would be shoguns themselves as main characters, and perhaps some of their loyal samurai or advisors.
Most likely, the main characters would be the shoguns themselves. For instance, Tokugawa Ieyasu would be a key figure if the story covers the Tokugawa shogunate. There might also be important samurai who served under the shoguns, like Honda Tadakatsu.
Since I don't know the exact 'Shogun Love Story', I can't say for sure. But it's likely to have a shogun as one of the main characters. There might also be a love interest, perhaps a court lady or a commoner.
