One plot idea could be that the main character, who has the dragon bloodline, teams up with Anko to face a new and powerful enemy in the Naruto world. This enemy could be after the power of the dragon bloodline.
Perhaps the dragon bloodline gives the character unique abilities like the power to control certain elements related to dragons, such as fire or wind. In the fanfiction, Anko could be initially skeptical but then come to rely on these powers. For example, they might have to battle a group of rogue ninjas who are causing chaos in the Hidden Leaf Village, and the dragon - bloodline abilities prove crucial in the fight.
One plot idea could be that Anko and Naruto are paired for a Chuunin Exams - like competition. They have to rely on each other's strengths. Naruto's ability to think on his feet and Anko's experience in tricky situations make them a formidable team. As they progress through the rounds, they develop a strong camaraderie and learn from each other's fighting styles.
Another idea is a story where Anko discovers a new power within Naruto that no one else has noticed. This could lead to her taking Naruto under her wing in a more personal training session, different from the ones he has had with Kakashi or Jiraiya. It could be a story of Anko helping Naruto unlock this hidden potential while also dealing with her own past traumas related to Orochimaru.
On the other hand, the Dragon Bloodline could also create some jealousy or tension. If the character starts getting a lot of attention because of their unique bloodline, Anko might feel a bit left out. However, as the story progresses, they could work through these feelings and develop a stronger, more equal relationship.
Well, a possible plot is that Anko's vampire nature gives her unique abilities that Naruto finds useful in a mission. They could go on a journey together to find a cure for her vampirism because Anko wants to be fully human again. Along the way, they face various challenges and their relationship grows from distrust to friendship.
Another plot could involve Anbu Naruto and Anko being on opposite sides of a conflict initially. But as they learn more about the true nature of the conflict, they realize they need to team up. Their relationship could develop from distrust to a strong bond as they fight together against a common enemy.
One plot idea could be that Dark Naruto, with his newfound power and darker nature, crosses paths with Anko. Anko, being a strong and somewhat mysterious character herself, could initially be on a mission to stop Dark Naruto. But as the story progresses, she realizes there's more to his transformation than just evil. She might try to understand the root cause of his darkness, perhaps related to the village's treatment of Naruto in the past. This could lead to an alliance between them against a common enemy within the village who wants to keep Naruto's power in check at any cost.
One idea could be Naruto teaching Anko a new jutsu. He could use his unique experiences and skills to help her expand her abilities. Another plot could involve them going on a mission together where Naruto has to rely on Anko's knowledge of certain areas or enemies. For example, Anko might be familiar with a particular type of snake - related enemy, and Naruto has to trust her expertise.
One idea could be a story where Anko, Naruto, and Omoi are on a joint mission. Maybe they have to retrieve a powerful and ancient artifact. Along the way, Naruto's positive attitude starts to rub off on the more serious Omoi, and Anko is there to keep them both in line with her tough - love approach.
In a fanfiction, you could have a scenario where an enemy uses a dark form of Bakuton bloodline power. Naruto and his comrades must find a way to counter it. They seek out an old hermit who has some knowledge of the Bakuton bloodline's weaknesses. Along the way, they learn more about the bloodline's connection to other elemental powers in the Naruto world, and how it can be used for both destruction and creation.
One idea could be a story where a character with the Shikotsumyaku bloodline discovers a new and powerful bone - related ability that no one in their clan has ever had before. This could lead to them being both feared and respected within the Naruto universe.
