Who Gave Him Permission to Leave the Ninja Village?

The future on the mountain is not from this world, and lives in a society far away from war. Now he has become a ninja because of the survival subsidy from the ninja school. Under the cruel rules of the ninja world, even food and clothing are a luxury; As a person who lives in a healthy society, he is full of doubts and disdain for this system that uses young children and teenagers as fighting tools. "Hokage-sama, I want to enroll in a ninja school." The midday sun shone through the window of the Hokage's office. Mirai looked at the Hokage, hiding the coldness in his heart, just smiling and bowing his head humbly. "Repay the favor to Konoha Hidden Village!" "I am Hokage, Sarutobi - Hiruzen." Sarutobi Hiruzen's eyes showed a trace of expectation and relief. He believed that this was the reason why Konoha continued to prosper. "I approve your request!" This is the beginning of my future as a ninja. It was also the beginning of the ninja's hurricane.
