The same story only a new beggining

Kakashi was born in Konoha but raised in Kirigakure (village hidden in the mist). Both his parents are alive, his best friend is Zabuza Momochi and killing comrades is in the daily basis. He also has to go on a certain mission to stop a certain bridge builder. Will meeting Obito, Naruto, Sakura and Sasuke change him? He also has a amazing sense of humor to make things better ;)
