Urgent! I Shiranui Genma Will Graduate Soon

Genma became Shiranui Genma of the Konoha Ninja School. His father, the breadwinner of the family, died and his mother was left to run a grocery store to make a living. The third war has begun, and he doesn't know when he will be called up. He is about to turn 10 and seems a little melancholy. War kills people! As for Shiranui Genma, apart from his pretty good Senbon Technique, there is nothing outstanding at all. After all, my father was just an outstanding chuunin who left behind only a few ninjutsu. In this dangerous and ungrateful ninja world, who knows if a team of jounin will suddenly pop up and destroy you. Just when Shiranui Genma was anxious, the door to the system's truth opened. "Tip!
