After transmigrating into the world of Naruto, he becomes Genma Shiranui, a ninja who is still attending the Ninja Academy, and later an examiner at the Chunin Exams, known for the "toothpick" in his mouth, as well as one of the Fourth Hokage's guards.
For Genma Shiranui, the good news is that the Second Shinobi World War is over. The bad news is that the Third Shinobi World War is waiting for him in the not-too-distant future. So he has to become a proper ninja before the war begins...
Of course, this is only the beginning. A world of ninjas awaits him.
Genma Shiranui: I need to correct one thing. The thing in my mouth... isn't actually a toothpick.
