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 ~😗
The theme of loss is also quite common. Since Kakashi lost his father early, many fanfictions explore how this affected his growth and decisions as a young ninja. Also, his development of his unique ninja abilities, such as the Sharingan, is a frequently explored theme in these fanfictions. For example, some stories might detail how he first awakened the Sharingan and how it changed his perspective in battles.
One reason could be the loss of his father. In the Naruto universe, Kakashi had a complex relationship with his father's death. If a fanfiction delves deeper into his younger years, this could be a very emotional trigger for him to cry.
One popular Kakashi in Young Justice fanfiction might be those that focus on his unique ninja skills being introduced to the Young Justice universe. For example, a story could revolve around him teaching the young heroes some of his stealth and combat techniques.
There could be a fanfiction where young Kakashi goes on a solo mission that was not part of the official storyline. He has to face challenges that test his skills and his mental strength. This could show his growth as a young ninja before he became as well - known as he is in the main series.
I'm not sure about specific 'lemon' fanfictions as they often involve inappropriate content. However, there are many great non - inappropriate fanfictions about Sakura and Kakashi that focus on their relationship in a more positive and platonic way, like those exploring their teamwork or Kakashi's mentorship of Sakura.
Well, the plot could involve Kakashi being a transfer student to Hogwarts. He might bring his ninja skills and unique perspective to the wizarding world. Maybe he'd form an unlikely friendship with some of the Hogwarts students like Harry, Ron and Hermione. His Sharingan could be an interesting addition, perhaps having some unforeseen interactions with magic.
I'm not sure about a specific 'young Kakashi crying' fanfiction off the top of my head. But you can try looking on fanfiction websites like Archive of Our Own. There are a ton of Naruto - related fanfictions there, and you might be able to find one that has this scenario.
Well, one possible plot could be that Naruto, having experienced so much growth himself, decides to pass on his unique ninja skills and values to a young Kakashi. He might teach Kakashi some of his signature jutsus like the Rasengan, but also lessons about friendship and never giving up. Naruto could also share his own experiences of dealing with loss and loneliness, which would be really interesting considering Kakashi's own past traumas.
One great young Kakashi fanfiction is 'The Young Protector'. It shows Kakashi's early days in the ninja world, his training, and his relationships with his comrades in a very engaging way.
