A great fanfic idea could be a time - travel story. Hinabi travels back in time to the Sekirei Plan's start and tries to change the outcome. She might use her knowledge of ninja tactics and her own abilities to outwit the forces at play in the Sekirei world. Or perhaps a story where Hinabi is mistaken for a Sekirei due to some strange power she develops, and she has to prove her true identity while dealing with the chaos that ensues.
One idea could be a crossover where characters from Naruto and Sekirei meet in a unique situation. For example, Hinabi could find herself in the Sekirei world and have to adapt to its rules while also using her ninja skills. Another idea is a story that focuses on Hinabi's training in a Sekirei - like setting, with new challenges and opponents that test her limits. Maybe she could form an unexpected alliance with a Sekirei character.
Some dedicated anime and manga fanfic communities might have Naruto Hinabi Sekirei fanfic. You could search for communities related to these series specifically. Additionally, Tumblr can be a source. There are many anime - loving bloggers on Tumblr who might write or reblog Naruto Hinabi Sekirei fanfic. However, the search on Tumblr can be a bit tricky, so you might need to use specific tags to narrow down your results.
One idea could be a Sekirei crossover with Naruto. Picture the Sekirei in the world of ninjas, having to use their powers in new and different ways. Another could be a crossover with Bleach, where the Sekirei interact with Soul Reapers. Maybe they could help in battles against Hollows or have their own spiritual powers explored in the context of the Bleach universe.
A possible plot could be that a group of evil forces in the Sekirei world sense Naruto's god - like presence and try to either capture or kill him. Naruto, being Naruto, decides to protect the Sekirei instead. He teams up with some of the strongest Sekirei and they form an alliance. As they fight together, Naruto starts to teach the Sekirei about friendship and loyalty, values that are important in his ninja world. This not only changes the Sekirei's perspective on life but also makes them stronger as a group. And along the way, Naruto might even fall in love with a Sekirei, which would add a romantic sub - plot to the story.
Well, the world - building in 'naruto sekirei fanfic' can be quite fascinating. The fanfic might blend the settings of the two universes, like the hidden villages from Naruto and the modern - day Tokyo - like setting of Sekirei. This creates a whole new backdrop for the story. Also, the character development is often interesting. Characters from both series can grow and change in ways that are different from their original storylines, which can add depth to the fanfic.
A possible plot is that there's a new threat that combines the dark forces from Naruto, like the Akatsuki, and the antagonists in Sekirei. Naruto and Miya Sekirei have to put aside their differences and work together. Maybe they start by sharing their respective combat techniques. Naruto could teach the Sekirei about chakra control, while the Sekirei could show Naruto some of their unique powers that could be useful in combat against this new threat.
One idea could be that Naruto, with his skills and determination, finds himself in the Sekirei world. He could form bonds with different Sekirei, like how he did with his friends in the Naruto world. Maybe he helps them in their battles and in the process, they all develop feelings for him.
A Sekirei and One Piece crossover would be cool too. Picture the Sekirei on the Grand Line. Their unique abilities would be a great addition to the already diverse world of pirates. They could join pirate crews as new members or cause chaos as they search for their Ashikabi among the pirates.
Another plotline might involve Hinabi's role in a post - war Hidden Leaf village. After all the chaos and destruction of the big battles in Naruto, she could be part of the rebuilding efforts. Maybe she uses her skills to help train the new generation of ninja or is involved in diplomatic relations with other villages.
One possible plot could be that Naruto somehow gets involved in the Sekirei Plan while still having the power of the Juubi within him. He might use his ninja skills and the Juubi's power to protect the Sekirei from those who would use them for evil purposes. For example, he could face off against Minaka Hiroto, the creator of the Sekirei Plan, if he discovers that the plan is causing harm to the Sekirei. Naruto's values of friendship and protecting the weak would likely drive his actions in this fanfic scenario.
Well, one interesting concept could be crossovers where characters from Naruto and Sekirei meet. For example, Naruto characters might be intrigued by the Sekirei Plan and try to interfere in a way that aligns with their own values of friendship and protecting the weak. Another concept could be the sharing of powers. Maybe a Sekirei could learn some of the ninja techniques from Naruto characters, like how to use chakra in a different way.
