What are some interesting plotlines in 'black blade naruto fanfic'?

One interesting plotline could be the origin of the black blade. Maybe it's a weapon created by an ancient shinobi clan with a special power. For example, it could be a blade that absorbs the chakra of those it cuts, making the wielder stronger.

One interesting concept could be the unique jutsu combinations. In fanfics, authors often create new jutsu by combining existing ones in Naruto, like a fire - water hybrid jutsu which is not in the original series. Another concept might be the character development of side characters. They can be given more depth and backstories, for example, making a minor character from the Hidden Leaf Village into a key figure in the fanfic's plot. Also, the concept of alternate universes is common. This allows for different power structures and relationships between characters, such as Naruto being raised in a different village and how that would change his character and the overall story.

One idea could be exploring the origin of the Totsuka Blade in the Naruto universe more deeply. Maybe it was created by an ancient clan with a special connection to the afterlife. Another idea is to have a character other than Itachi use the blade in a completely different way, like a young ninja who discovers its power accidentally.

One interesting plotline could be the exploration of Onikage's backstory within the Naruto universe. Maybe he has a hidden connection to a powerful clan that was long forgotten.

One interesting plotline could be the exploration of the unique culture and history of the Mist Village within the fanfic. Maybe it delves into the training methods of Mist ninjas that are different from other villages.

One interesting plotline could be about Naruto exploring an alternate universe within the Samsara concept. Maybe he discovers new powers or meets different versions of his friends.
