Half a year later.
"Uchiha Jin, you can't kill me!"
Late at night, a middle-aged Jonin was cornered against a wall, his body bearing several wounds. He clutched his bleeding abdomen with one hand and panted heavily.
"I'm a Jonin of this village! I've shed blood for this village! I'm a hero of this village!"
Under the moonlight.
Uchiha Jin slowly approached, Tachi in hand.
"It wasn't easy catching a big fish like you. How could I let you leave?"
He stared at the red health bar above the man's head, his eyes filled with a longing for Justice Points.
This ninja was named Yamada Ichiro, and he came from a civilian background.
Some time ago, he had killed his wife and son while drunk, then disposed of their bodies and hidden them away.
He had told others that his wife had taken their son to visit her family.
If Uchiha Jin hadn't stumbled upon him during a patrol.
He would have almost missed him.
And those weren't Yamada Ichiro's only crimes. He had also killed three members of his squad.
All because the mission pay hadn't been divided evenly.
During the mission, he had launched a surprise attack while his teammates were off guard, killing all three before claiming they had been ambushed along the way.
Without witnesses or physical evidence, the village could only accept his account of how the three had died.
Ultimately, ninja weren't really good people.
Uchiha Jin had never considered himself a good person, either.
After all, in a world where might made right, the powerful really could do whatever they wanted.
Yamada Ichiro was a Jonin. Killing three comrades had been easy for him...
Without the system, Uchiha Jin could never have learned about this, nor would he have come to kill him
