Another reason could be related to his personal growth. He might be trying to master the power of the eye in private. Naruto has always been one to face challenges alone at first. By hiding his eye, he can focus on understanding and using its power without distractions or the pressure of others' expectations.
One consequence could be that his friends might start to suspect him. Since Naruto is usually an open book, hiding something as significant as his eye could make them wonder what he's up to.
They might be a council - like group of elders in the Naruto fanfic world. They possess great wisdom when it comes to eye - related matters. They could be the ones who decide who is worthy of inheriting certain eye powers or who can be trained in advanced eye - based jutsu. Their role might be to maintain the balance of power in the world regarding eye techniques, and they could be either allies or antagonists depending on the plot of the fanfic.
Well, it could be about a fan - created story in the Naruto universe that focuses on the so - called 'eye of the elders'. Maybe it involves some unique powers or a hidden story related to this special eye that the elders possess. However, without reading it, it's hard to say exactly what it's about.
There's also the possibility that it's an accidental injury caused by one of Naruto's friends during a training session gone wrong. For example, Sasuke could accidentally unleash a jutsu that hits Naruto's eye while they are sparring.
Perhaps Naruto is waiting for the right moment to reveal his skills for maximum impact. He could be planning a big surprise for his enemies or wants to make a grand entrance at a crucial time. For example, in a major battle against a powerful foe, he could suddenly unleash all his hidden skills and turn the tide of the battle, which would be more effective than showing them off gradually.
Maybe he wants to protect his loved ones. If his enemies know his true strength, they might target his friends and family to get to him. So, by hiding his skills, he can keep them out of harm's way while still being able to fight when necessary.
Well, she could start by dressing in a more androgynous way. Maybe wearing loose-fitting clothes that don't give away her feminine shape. Also, she might try to lower her voice or use certain speech patterns that are more associated with males in that fictional world.
She might want to prove herself in a male - dominated ninja world. If she shows herself as female, she could face discrimination or be underestimated. So, hiding her gender gives her a chance to be seen as an equal to male ninjas.
He could practice in secret locations where no one can see him. For example, in an abandoned cave or a hidden part of the forest. That way, no one will know about the new jutsu he's developing.
One consequence could be that Naruto becomes more isolated. He may feel like he's a burden or that he's not as strong as he used to be. However, this could also lead to him becoming more determined to overcome his disability. He might train harder to develop his other senses, like his hearing and sense of smell, to make up for the loss of his eye. This could ultimately make him a more well - rounded and unpredictable fighter.
