Definitely Naruto, as he always finds a way to overcome challenges, and with the Demon Eyes Kyo, he could reach new levels of power and face even greater threats. Sakura could also be an interesting character to include. She has grown a lot in strength and her medical ninjutsu skills could be combined with the power of the Demon Eyes Kyo in unique ways. Rock Lee is another candidate. His hard - working and never - give - up attitude could be put to the test when dealing with the power and the potential danger of the Demon Eyes Kyo.
One possible reason could be that his eyes hold a special power that he doesn't want others to discover easily. For example, it might be a new type of Sharingan or a unique ability related to his Uzumaki heritage that he needs to keep secret to protect himself or those around him.
In a Naruto fanfiction with red eyes, he might gain this trait as a result of a new power-up. For example, he could encounter a powerful sage or a mysterious entity that bestows him with this red - eyed form. His abilities would likely change as well.

His friends might be initially shocked but would soon accept this new Naruto as he uses his powers for the good of the village.
One popular 'Naruto different eyes fanfic' idea could be about a character having a unique eye power that combines the Sharingan and Byakugan.

This could lead to interesting battles and strategic maneuvers within the Naruto universe.
In some stories, the fox eyes might give Naruto a kind of hypnotic or intimidating power. Enemies might be momentarily stunned or less able to fight effectively when they look into his fox eyes. This could be a unique advantage in battles, allowing Naruto to gain the upper hand without having to use as much physical force.
His relationships with his friends might become stronger. Since he can see more clearly with his god eyes, he can better protect them. His friends would trust him more knowing he has this extra power to keep them safe.
One great fanfiction is 'The Fox - Eyed Naruto' on FanFiction.net. It really delves into how Naruto's fox - eyed appearance changes the way people perceive him in the village. The author does an amazing job of integrating this new physical trait into the existing Naruto universe storyline.
His friends might react with shock and confusion. They might not understand why he has been hiding this from them, and it could cause a rift in their relationships until he explains the reasons behind it. For example, some friends might feel betrayed that he didn't trust them enough to share this secret.
