Sure, Kakashi is present in the Boruto manga. His role might not be as prominent as in the Naruto series, but he still has significant moments and interactions.
I recommend "I am the Second Young Master of the Flagwood Family" to you. The main character of this novel, Flagwood Miren, transmigrated to the Naruto World and became the second young master of the Flagwood Family. He is the same age as Kakashi. The plot of this novel also included other Naruto characters, such as Haki Shuogu, Ban, and Bo Fengshui Gate. I hope you like this fairy's recommendation. Muah ~😗
Kakashi would probably be very calm at first. He's an experienced ninja who has seen a lot. He'd gently pat Naruto on the back, offering silent comfort. Then he might start to speak softly, asking Naruto what's wrong in a gentle voice.
Kakashi provides a sense of stability. Naruto has a somewhat chaotic life, but Kakashi is a constant presence. He's like a father figure in a way. He's always there when Naruto needs advice or just someone to be around. This stability helps Naruto feel more secure and less alone in his journey as a ninja.
Well, for starters, Kakashi has to deal with Naruto's hyperactive and sometimes reckless behavior. Naruto often acts without thinking, which could put him in danger. Sasuke, with his complex emotions and the burden of his clan's massacre, is also a handful. Kakashi needs to make Sasuke understand that revenge is not the only way forward. Additionally, Kakashi has to ensure that both Naruto and Sasuke get along well with each other. There could be rivalry between them, and Kakashi has to manage that in a way that doesn't harm their relationship or their growth as ninjas.
She might learn some advanced jutsu. For example, Kakashi could teach her his famous Chidori, which is a very powerful lightning - style jutsu. This would significantly enhance Sakura's combat abilities.
In a Sakura and Kakashi time travel fanfiction, they could end up in the past during a major war. Kakashi would be a great asset with his Sharingan and combat skills. Sakura, on the other hand, could help the wounded soldiers. Their presence in the past could change the outcome of the war. For example, they might be able to save some important characters who were supposed to die. This would then lead to a completely different future when they return to their own time.
A powerful Kakashi fanfiction often has a deep exploration of his character. It shows his inner thoughts, his insecurities, and his determination. For example, if it delves into his feelings about his father's death and how that influenced his growth.
