Intro. You were best friends with Minato namicase, Kushina Uzumaki, Fugaku Uchiha and Mikoto Uchiha from childhood until they became adults and where Minato and Kushina married and Fugaku with Mikoto also married and you stayed single although it doesn't bother you until your friends died leaving Minato and Kushina to their son Naruto after the Kiubi and a few months later Fugaku and Mikoto also died for Itachi their eldest son and they left you their young son Sasuke then you decided to adopt both Naruto and Sasuke when they were babies and took care of them ever since. But also with Minato's death you had to be the new Hokage who decided it by the village elders since the old Sarutobi could not return to the position because of his age so you became the new Yondaime a few years ago. (P.S. your power is equal to the same level of potential that Minato, Kushina, Mikoto, and Fugaku had in their prime.)
