He may be using some sort of sealing jutsu on himself. This jutsu could be something he learned or developed himself. The sealing jutsu would keep his true power locked away and prevent it from being sensed by his parents. It's a more long - term and secure way of hiding his power compared to just suppressing it.
Naruto might be faking his skills and abilities in front of his parents. So instead of showing his real power in combat or training, he acts as if he's at a much lower level. He could be making intentional mistakes or not using his full potential during sparring sessions with his parents.
He could be using basic chakra control techniques to suppress his power. By constantly regulating the flow of his chakra, he can keep his true power hidden. For example, he might be using a form of internal chakra suppression similar to what some ninja use to hide their presence.
Another possibility is that Naruto has his own plans and goals that he wants to achieve independently. His true power might be a key factor in these plans, and he doesn't want his parents' influence or interference. He wants to prove himself on his own terms, without relying on his family connection.
He might use simple language on purpose. For example, he could pretend to be confused about things he actually understands well. He may also make silly mistakes intentionally to give the impression that he's not as smart as he really is.
He might put on a fake smile and act normal. Naruto is good at being energetic on the outside, so his family may not suspect that he's in pain.
Well, in fanfictions, often the plot takes a different turn. Naruto might hide from his family because there could be some sort of misunderstanding. For example, there could be false rumors about him being involved in something bad. And he might think that his family would believe those rumors without giving him a chance to explain. So, to avoid the immediate confrontation and judgment, he chooses to hide.
To gain an advantage. Just like in the original series where he often used surprise to his benefit. In fanfiction, hiding his power allows him to do the same. He can catch his opponents off - guard.
In many fanfictions, Naruto might hide his pain by putting on a big smile. He's always been the type to try and be positive in the face of his friends. He could also distract others with his goofy antics, like making a joke or doing something silly to shift the focus away from his inner turmoil.
Well, in some fanfictions, it could be during a life - or - death battle. Maybe when he's facing an extremely powerful enemy that he can't defeat with his known abilities. His friends could be in great danger, and that intense situation triggers the revelation of his hidden power.
Well, he might use simple distractions. For example, he could create a minor commotion to draw attention away when he's about to use a particular skill subtly. Maybe he pretends to be clumsy or make a small mistake on purpose so that others don't suspect he has advanced skills.
He might use some special jutsu or seals. For example, he could use a sealing technique to suppress the signs of his bloodline. This way, others wouldn't be able to detect it through normal means like sensing chakra.
In the original, Naruto's relationships are mainly with his friends, teachers, and the village. But in this fanfiction, his relationship with his parents, which is non - existent in the original, becomes central. This completely alters the way we perceive Naruto and the world he lives in. It's a significant deviation from the source material that allows for a very different exploration of Naruto's character.
