Naruto: Kakashi's Second Chance with the System

Death wasn't the end—it was a new beginning. Killed during Pain's devastating attack on Konoha, Hatake Kakashi awakens with an impossible gift: the Escape-One System and a chance to rewrite history. Sent back to his younger self, he carries the weight of every loss—his father's suicide, Obito's sacrifice, Rin's tragic end, Minato-sensei's death. Armed with system powers that can alter fate itself, Kakashi refuses to let tragedy repeat. This time, he'll save everyone. This time, no regrets.
