Kakashi Hatake is a character in the Naruto and Boruto anime and manga series. In Boruto, Kakashi is shown as being an adult and the Sixth Hokage of the village of Konoha. It is not explicitly stated how old Kakashi is in Boruto, but it is likely that he is in his late 30s or early 40s.
In the original Naruto series, Kakashi is shown as being an adult and a skilled ninja. He is the teacher of the main character, Naruto Uzumaki, and his teammates Sasuke Uchiha and Sakura Haruno. Kakashi is known for his calm and collected demeanor, as well as his use of the Sharingan eye, which he inherited from his former teammate Obito Uchiha.
In the Boruto series, which takes place many years after the events of Naruto, Kakashi has retired from active duty as a ninja and has taken on the role of the Sixth Hokage. He is still a skilled and respected ninja, but is also shown as being more laid back and relaxed than he was in the original series.
