He could use it for stealth. For example, he could create paper clones that are much quieter and less detectable than his normal clones. These paper clones could be used to spy on enemies or gather information without being noticed easily.
Naruto might use paper jutsu for defense. He could form a shield made of tightly packed paper that is strong enough to block incoming attacks. The paper could also be manipulated to wrap around opponents, restricting their movement much like a net. Additionally, he could send out sharpened paper shurikens that are more difficult to detect than normal ones, giving his attacks an element of surprise.
Well, in certain fanfic scenarios, Naruto could learn paper jutsu as a result of some experimental training. For example, he might be trying to combine different elements of his existing jutsu and accidentally discovers a way to manipulate paper. It could be that his chakra takes on a new form during a particularly intense training session and he realizes he can control paper with it.
One possible application is for stealth and deception. Naruto could use the ink to create illusions of himself or other objects, confusing his enemies. For example, he could make it seem like there are multiple Narutos on the battlefield.
It could be a new form of Rasengan. Maybe Naruto discovers a way to combine different elements with the Rasengan more effectively, like adding lightning to it for a more powerful and faster attack.
One possible plotline could be that Naruto discovers this new jutsu during a difficult battle. He then uses it to turn the tide of the fight, much to the surprise of his opponents and allies alike.
Naruto could use chakra strings in fanfiction for communication. He might be able to send vibrations through the strings to other ninja who are also attuned to chakra, like a secret code. Also, in combat, he could use the strings to set up traps. He could string them across a path and when an enemy steps on them, he can either trip the enemy or use the connection to launch a surprise attack.
There could be a jutsu that allows for instant teleportation across long distances. This jutsu might be a new discovery in the fanfiction world, perhaps created by a character who has been experimenting with space - time ninjutsu. They might use it to quickly get in and out of battles or reach far - off places in a blink.
He could use it for defense. For instance, creating a huge storm to block enemy attacks or a thick fog to hide his village from invaders.
A potential new jutsu could be 'Rinnegan - Hyton Ice Storm'. Naruto would first use the Rinnegan to sense the surrounding area and locate his enemies. Then, he would use his Hyton to create a powerful ice storm. The storm would be filled with shards of ice that are not only sharp but also infused with chakra from the Rinnegan. This would make them extremely difficult to defend against. Another jutsu could be 'Hyton - Rinnegan Ice Shield'. He could use his Hyton to create a large ice shield and then use the Rinnegan to reinforce it, making it capable of withstanding powerful attacks.
Well, 'accounting no jutsu' in Naruto fanfiction might be a unique concept created by fans. It could be that this 'jutsu' involves using numbers and calculations in a way similar to accounting in the Naruto universe. Maybe it's a way for a character to keep track of resources, like how much chakra is being used in a fight or how many supplies are left in a mission, in a very precise and calculated manner.
Well, 'Mokujin no Jutsu' in Naruto fanfiction could be a very unique and interesting concept. It might be related to the idea of creating wooden constructs or using wood in a way that we haven't seen in the official Naruto storyline. Maybe it gives the user the ability to control wooden puppets like a more advanced version of Kankuro's puppet jutsu, but with a wood - element twist.
