Reborn in the Naruto world, becoming Shiranui Genma who is still studying at the ninja school—the examiner who held a toothpick during the Chunin exam, and one of the guards of the fourth generation of Hokage. For Shiranui Genma, the good news is the Second Ninja World War
It's over, and the bad news is that the third ninja war is waiting for him in the not-too-distant future. Therefore, he must become a qualified ninja before the ninja war comes... Of course, this is just the beginning, welcome
His will be a world of ninjas. Shiranui Genma: I want to correct one thing, the thing in my mouth...is not actually a toothpick.
