I Came to the Ninja World with Thunder and Lightning in My Arms

I carried thunder and lightning and traveled to Hokage, becoming the brother-in-law of the Fourth Hokage. My little brother, I studied under the Third Hokage Sarutobi Hiruzen, Minato's nephew. From now on, I will call you nephew, and you will call me brother. We both have our own things to do. Sarutobi-sensei, remnants of the old era, stop coming to the new era to point fingers! My dancing skills are even better than Madala's! Ps: Naruto, Konoha, Ninja World
