Traveling through the world of Naruto, he became the examiner holding a "toothpick" in his mouth during the chunin exam of Genma Shiranui, who was still studying in the ninja school, and one of the guards of the Fourth Hokage.
For Shiranui Genma, the good news is that the Second Ninja War is over, and the bad news is that the Third Ninja War is waiting for him in the near future. Therefore, he must become a qualified ninja before the great ninja war comes...
Of course, this is just the beginning, what will greet him will be a world belonging to ninjas.
Shiranui Genma: I want to correct one thing. The thing in my mouth... Is not actually a toothpick.
