Just Became Hokage on the First Day!

[True invincibility + (none) single female protagonist + decisive killing + Naruto] Hatake Naoya, the successor of the Snake Heart Sword, went out directly after the Second Ninja War and wiped out the entire Otsutsuki clan. As a result, after he came back, his eldest brother Hatake Sakumo committed suicide after being framed? Since Konoha is in darkness under your leadership, then open a new road in my hands! Isn't he just a Hokage? I did it! (I let someone else do it!) {The story plot is fast and the overall style is more daily. There won't be too many fighting scenes, they can basically be solved with just a few moves. Invincibility also has the loneliness of being invincible~}
