An interesting plot could be that Anko discovers a hidden ability within Naruto that not even he was aware of. It could be related to an ancient ninja art that has some connection to Anko's family. They then go on a quest to learn more about this ability. Along the way, they face various challenges, like traps set by an unknown enemy who doesn't want them to uncover the secrets of this power. As they progress, they also have to deal with their own personal demons. Naruto has to overcome his fear of not being in control of this new power, and Anko has to face her past traumas related to Orochimaru that resurface during the journey.
A possible interesting plot could be that a powerful villain is trying to merge the two worlds, Fairy Tail's world and Naruto's world, into one chaotic mess. Lucy and Naruto are brought together by fate to stop this. They start off not trusting each other much as they are from very different backgrounds. But as they face challenges together, like battling the villain's minions who have a mix of magic and ninjutsu abilities, they begin to respect and rely on each other. Eventually, they discover that the key to stopping the villain lies in combining Lucy's celestial magic with Naruto's Sage Mode powers.
The plot of this fanfiction might involve Naruto's banishment being part of a larger conspiracy. Anko discovers this and decides to help Naruto clear his name. They go on a quest to find evidence that will prove his innocence. During their travels, they develop a deeper bond. Naruto might struggle with feelings of betrayal from his village, while Anko tries to keep his spirits up. Their journey could be filled with emotional turmoil and exciting ninja battles as they face the forces behind the conspiracy.
Well, perhaps a plot where Anko discovers a dangerous curse that could potentially harm the village. She enlists the help of Naruto, known for his determination and strength, and Hana, with her connection to the ninja dogs for tracking. They journey to find the origin of the curse. During this journey, Naruto's positive attitude starts to rub off on Anko, who is usually a bit more brooding. Hana, on the other hand, uses her skills to keep them safe from various threats they encounter in the wild.
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.
Often, a plot point is Anko's past traumas and how Naruto helps her heal. For example, her experiences with Orochimaru. Naruto's kind heart and his own experiences of being an outcast in a way allow him to understand her pain. This mutual understanding can be a strong bond in the relationship.
In a crossover, it could be that the zombie apocalypse has hit the Naruto world as well. Naruto, being the hero he is, decides to find a cure. He teams up with some of the characters from The Walking Dead who have knowledge about viruses. Sakura uses her medical ninjutsu to study the walkers, while Naruto uses his strength and speed to protect the group. They search for a way to reverse the zombification process and restore peace to both worlds.
One possible fanfiction could start with Naruto being sent on a special mission in the Hidden Leaf Village. He stumbles upon Anko in a training ground. Anko, being the tough and experienced ninja she is, initially challenges Naruto. But Naruto, with his newfound strength and determination, impresses her. They then team up to face a new threat that has emerged on the outskirts of the village, a group of rogue ninjas with strange powers. As they fight side by side, they learn from each other's fighting styles and develop a mutual respect that could potentially turn into a deeper friendship or more as the story progresses.
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.
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.
The relationship would be an interesting blend of two very different personalities. Naruto is often upbeat and optimistic, while Anko has a more edgy and somewhat cynical side. However, they would balance each other out. Naruto would bring out the softer side of Anko, and Anko would keep Naruto grounded. They would have a deep emotional connection based on shared experiences and a growing love for each other. For example, Naruto might share his dreams of a better future for the village with Anko, and she would offer her own insights and experiences to help him achieve those dreams. And in their private moments, they would have a very affectionate and understanding relationship.
