The sentient sword could also have a tragic past. Maybe it was once used for evil and now wants to atone by helping Naruto. It could share its knowledge of ancient jutsu or forgotten battles with Naruto, which would give Naruto an edge in his future fights.
Another scenario is that the sword has a connection to an old enemy or a hidden organization. When Naruto discovers this, he has to decide whether to keep the sword or get rid of it. This could lead to a moral dilemma for Naruto as he may have grown attached to the sword already.
One possibility is that the sentient weapon has its own goals and motives. It could lead Naruto on a quest to fulfill something it desires. For example, it might need to be reunited with its original creator or find a special place. Naruto would likely go along with it, seeing it as an adventure and also because he trusts his instincts about the weapon not being evil right away.
He might start training with it. Naruto is always eager to improve his skills, and a new sword could be a great addition to his combat abilities.
Well, he could gain new powers. Maybe the sentient library has books that teach him long - lost jutsu or give him knowledge about the nature of chakra that no one else in the ninja world knows. For example, he might learn how to combine different elemental chakra in a completely new way.
Well, he might discover that the sword has some special powers. Maybe it can cut through any material, or it could have the ability to absorb chakra. He could start training with it to become even stronger in battle.
He could use it to discover more about his Uzumaki heritage. Maybe the sword has some special powers or markings that are related to the Uzumaki clan. It could also put him in danger as others might be after the sword for its power or value.
Well, Naruto could have a powerful new ally. The sentient sword might be able to communicate with Naruto, giving him advice in battles. It could also have special abilities like being able to cut through any material, which would be a great advantage for Naruto.
In a fanfiction scenario where Naruto finds a lightsaber, he could potentially incorporate it into his fighting style. He's always been creative in combat. He might use his ninja skills like speed and agility along with the lightsaber's unique capabilities. For example, he could use his shadow clone jutsu and have his clones all wield the lightsaber in different ways to confuse his enemies.
He might meet someone who is also after the scythe. This could lead to a conflict or an alliance. If it's an enemy, Naruto will surely fight to keep the scythe. But if it's someone who can help him understand the scythe better, they could team up and go on adventures together.
Another possibility is that the robot is from a future where ninjas no longer exist. It could be sent back in time for some reason, and Naruto is the key to its mission. The robot might need Naruto's help to change something in the past to ensure a better future. Naruto, being the hero he is, would likely take on this challenge without hesitation, leading to a whole series of exciting adventures.
Naruto could find a book that tells the story of a great hero who was just like him, full of energy and a desire to protect. This could inspire him to new heights. He might also accidentally trigger a trap or a hidden mechanism in the library while exploring, leading to an adventure filled with challenges and puzzles to solve.
