For a 'Naruto Blood C' fanfiction, you could have a scenario where Naruto himself is turned into a half - Elder Bairn due to some dark magic or experiment gone wrong. This would cause him to struggle with his new nature while still trying to uphold his ninja values. His friends from Konoha would have to figure out how to help him without killing him, and they might also have to deal with the other Elder Bairns who see Naruto as a new threat or a potential ally.
A cool 'Naruto Blood C' fanfiction idea could be that the Akatsuki organization somehow gets involved with the events in Blood C. They might be interested in the power of the Elder Bairns or the unique blood in Saya's veins. Or perhaps a Naruto character, like Sasuke, becomes an ally to Saya and teaches her some of his Sharingan - related combat techniques in exchange for her knowledge about the Blood C world.
One idea could be a crossover where Naruto characters are transported to the world of Blood C. Naruto's ninja skills could be pitted against the Elder Bairns in some epic battles. Another idea is to explore what would happen if a character from Blood C, like Saya, gained the ability to use chakra like in Naruto. Maybe she could use it to better fight against the monsters she faces in her own world.
Well, one interesting plot idea could be a barfly character who has some unique knowledge about the Naruto world. Maybe they know secrets about certain jutsus or the history of the hidden villages that no one else does. This could lead to an adventure where the main Naruto characters have to interact with this barfly to uncover the truth.
One interesting idea could be a character who can manipulate their blood to create powerful defensive shields. For example, they could form a blood - based armor that is not only strong but also has unique properties like being able to absorb chakra attacks. Another idea might be a ninja who uses blood manipulation to track enemies. By leaving a tiny trace of their blood in an area, they can sense when an enemy comes in contact with it. It could also be used for stealth, as they can control the flow of their blood to lower their body heat and become less detectable.
One idea could be a character who discovers they have blood - bending abilities in the Naruto universe and has to hide it from their village at first. Maybe they are from a non - water - based village and fear being ostracized. Another plot could involve a blood - bender using their power to heal instead of harm, which goes against the traditional view of blood - bending in other fictional universes. A third idea might be a blood - bender who gets caught in the middle of a war between two great ninja powers and has to decide which side to use their power for.
Well, a plot idea could involve Haren being framed and sent to the Blood Prison. Once there, he uncovers a conspiracy that reaches outside the prison walls. He then has to find a way to expose it while dealing with the prison's internal power struggles and dangerous inmates. This could involve using his wits and any latent ninja skills he might have.
A great plot idea would be a tournament where characters from both Naruto and Strike the Blood participate. Naruto's friends like Sasuke and Sakura could also be brought into this new world. They would have to learn the rules of the Strike the Blood world quickly and use their ninja skills to compete. The vampires in Strike the Blood might be intrigued by the ninja powers and try to learn from them. This could lead to some interesting alliances and rivalries.
Perhaps a story where the Blood Blockade Battlefront technology is somehow misused by an enemy. Naruto and his friends have to figure out how to stop this misuse and also learn about the true nature of this technology along the way. They might face challenges like dealing with altered versions of their known jutsus due to the technology's interference.
One idea could be that they discover they are blood brothers during a dangerous mission. This revelation then changes their entire dynamic and they start to fight side - by - side with a new level of unity. Another could be that there is a hidden prophecy about the two of them as blood brothers saving the ninja world in a unique way that no one else could.
One idea could be the main character having to protect the harem members within the dangerous Blood Prison setting. Maybe there are secrets about the prison that only the harem members know, and they rely on the main character to uncover them while fending off other threats.
A third plot idea is a character - swap scenario. What if Kojou Akatsuki wakes up in the Naruto world with his vampire powers? He would have to navigate the world of ninjas, clans, and hidden villages. Meanwhile, Naruto could end up in the Strike the Blood world, having to deal with the complex politics between the different vampire factions while also trying to find a way back home.
Perhaps a fanfic where Naruto's blood has some special connection to an ancient and powerful demon. The demon is slowly being awakened due to some dark magic related to Naruto's blood. Naruto has to face not only the threat of the demon but also the distrust from some in the village who think his blood is a danger. He must prove that he can control this situation and keep the village safe.
