Yes, there are some. You can start by looking on fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'naruto is shino's mate' in their search bars and you'll likely find a variety of stories with different takes on this pairing.
One common theme is friendship evolving into something deeper. Since Naruto and Shino start as comrades, the fanfictions often show how their bond changes. Another theme could be acceptance, as they come from different backgrounds in the Naruto world.
In fanfiction, Naruto and Shino's friendship can be really interesting. Naruto's exuberant personality contrasts with Shino's more reserved nature. For example, Naruto might be the one to drag Shino into all sorts of adventures, while Shino would use his intelligence and bug - related skills to get them out of trouble. Their friendship could also develop over training sessions, with Naruto learning about Shino's unique abilities and respecting him more for it.
In a fanfiction regarding Shino's eyes, his eyes might be the key to an ancient shinobi technique. For example, his eyes could unlock a hidden jutsu that was lost for centuries. This jutsu could be related to insect control in a more profound way, like being able to communicate with all insects on a spiritual level, not just the ones he summons. This would give him a huge advantage in both intelligence - gathering and combat.
Well, in some fanfiction, their friendship is shown as a slow - burning one. Naruto doesn't quite understand Shino at first because of his bug - like appearance and quiet ways. But as they work together on missions, Naruto begins to see Shino's loyalty and strength. Shino, on the other hand, admires Naruto's determination.
They could start by sharing common goals. For example, they both want to protect Konoha. Working towards this goal side by side can bring them closer. They might have conversations during their guard duties about their dreams and fears.
If adopted by Shino in fanfiction, Naruto's character could change in several ways. For one, he'd likely become more attuned to nature, since Shino has a strong connection to the bugs in nature. Also, his fighting style might become more strategic and less brute - force - oriented. Shino could teach him to use his surroundings and opponents' weaknesses better. And Naruto's sense of family might shift. Instead of always longing for the acceptance of the village as a whole, he'd have a more personal family unit with Shino, which could make him more content and less desperate for validation from others.
One idea could be a story where Naruto and Shino go on a mission together. Shino's calm and calculating nature complements Naruto's impulsive and energetic style. They face a powerful enemy that requires both of their skills to defeat. For example, Naruto uses his shadow clones to distract the foe while Shino uses his bugs to find the enemy's weak points.
Another theme is his bug abilities. Fanfictions often expand on how his bugs can be used in different ways, like for espionage or in unique battle strategies. For instance, there are stories where Shino uses his bugs to solve mysteries within the village. Also, his relationship with other characters, especially his team members, is a common theme. Some fanfictions focus on how he interacts with them and how they influence his growth as a ninja.
There's also 'Naruto and Shino: A Different Kind of Teamwork'. It's not just about the romance but also how their relationship affects their roles in the ninja world. It's a bit more complex and has some interesting plot twists that add depth to the Yaoi relationship.
