There might also be an outcast blood member. This character has been shunned by the clan for some reason, but still has a connection to it. Their struggle to either find their place back in the clan or break free completely can add depth and drama to the story.
Perhaps a story where a blood member has to prove their worth to the clan in the face of a great threat. They might have to undergo difficult trials and form unexpected alliances with other members to save the clan from destruction.
I don't know for sure as it depends on the specific fanfic. It could be the clan leader as a main character, who has to make important decisions for the clan. Maybe there's a young and talented member who is trying to prove themselves within the clan.
Well, we can assume Aruto. Then, there could be a female character from the clan who has some special abilities and she becomes an important ally of Aruto. Also, there might be a traitor within the clan who is trying to undermine the rebirth process, and this character would add a lot of drama to the story as Aruto tries to figure out who it is and stop them.
Well, it often depends on the specific fanfic. But usually, there's the character who discovers or is given the Blood Quill. This character could be a young and curious wizard or witch.
I don't know as I haven't read it. But they could be adventurers or treasure hunters interested in the blood emeralds.
Typically, there's the protagonist who often has a special connection to the dragon blood. This character might be on a journey to discover the true meaning and power of their dragon blood heritage. There could also be a mentor - like figure, someone who has more knowledge about the dragon blood and its implications. And of course, there are usually antagonists who either want to control the power of the dragon blood for their own evil purposes or are afraid of those with the dragon blood and try to eliminate them.
Often, the main character is a young and brave member of the Lion Clan. They might be an outcast or a prodigy within the clan.
A female shinobi who defies the traditional gender roles in her clan during the wars would make an interesting main character. She could break barriers and show that women can be just as powerful and important in the shinobi world as men, and her actions could have a significant impact on the outcome of the clan wars.
Since I haven't read the specific fanfic, it's hard to say. But it could be the elders themselves, or perhaps a young ninja who discovers something about the elders' blood and becomes central to the story.
In 'Alice and Blood' fanfics, Alice is typically the protagonist. The other main characters can vary. Sometimes there are vampire hunters who think Alice is in league with the vampires because of her connection to blood. Or there could be a vampire elder who has a special interest in Alice, either to protect her or to use her for some blood - related purpose.
