Kakashi's back story is gradually revealed throughout the Naruto series. You'll get to know more about his past as the story progresses.
The details of Kakashi's back story are disclosed at different points in the Naruto storyline. It's a complex and interesting tale that unfolds over time. There are specific arcs and episodes dedicated to exploring his history.
Well, one main event is his relationship with his father. His father was shamed for choosing to save his comrades over a mission. This had a big impact on Kakashi. Another important part is his time with Obito and Rin. Obito's 'death' was a turning point for Kakashi, and he got his Sharingan from Obito then.
The key events in Kakashi's back story start with his father's misfortune. Sakumo Hatake's death left Kakashi with a sense of duty and the need to be a perfect ninja. Then, the mission where he, Obito and Rin were involved. Obito's sacrifice and Kakashi's gain of the Sharingan. His time in ANBU, which exposed him to the darker side of the ninja world. And later, his role as a mentor to the new generation of ninjas, like Naruto, Sasuke and Sakura.
The episodes that focus on Kakashi's back story are mainly in the arc where his past is explored. But it's a bit hard to pinpoint specific ones exactly.
Well, Kakashi's back story involves his early days as a ninja. His father's death had a huge impact on him. He was then trained hard to be a great ninja. He was put in a team with Obito Uchiha and Rin Nohara. During a mission, Obito 'died' (or so it was thought at first) and Kakashi got his Sharingan. This event also added to his complex character. He had to deal with the loss of his friend and the new power he got. He later became a mentor to Naruto and his friends, using his own experiences to guide them.
Kakashi's back story influenced his character in multiple ways. The death of Obito and Rin filled him with guilt and a sense of responsibility. He started to value his comrades more, which was a big change from his earlier more mission - focused self. His experiences also made him more empathetic towards others. He saw the pain and loss that war could bring, and this changed his approach to both life and combat. He became a more complex and nuanced character as a result of his back story.
Doflamingo's back story is told during specific arcs in the One Piece series. You'll find out as you progress through the storyline.
With Minato, Kakashi's relationship could also shift. If Sakumo is alive, Kakashi may not be as eager to prove himself in the same way. Minato might see a different side of Kakashi, one that is more at peace with himself. This could lead to a more mentor - mentee relationship based on mutual respect and understanding rather than Kakashi's need for validation.
Since Naruto has more knowledge of the future, Kakashi might start to rely on him more, which could shift their relationship. Naruto could also see a different side of Kakashi from the past, and this new understanding could deepen their connection. For example, they might have to face some challenges together that make them trust each other more than before.
Their relationship might not change much directly. Kakashi reading Jiraya novels is more of his personal interest. But Kakashi could share some interesting parts from the novels with Naruto, which might make Naruto feel closer to Kakashi as they both have a connection to Jiraya in different ways.
