Shiny_Shirogane

Klautz had lived his whole life as a ninja... as a tool.
Yet before dying he had killed all of ninjas of his clan. He had defied the ninja code and acted on his own discretion. A code he had followed his entire life.
Even in his dying moments he had chosen a harsh death.
*Whoosh*
Suddenly, Klautz opened his eyes. By some miracle, he was still alive. He then realized that he had actually gone back forty years in time.
"I will wipe out all of the ninjas from the face of HELL!" 

Join him as he fulfill his desires and his goals, all of which he wasn't able to do before.

Shinobi From Hell

"Rest in peace," Klautz whispered. But there was no malice towards the man in his words. The man squirmed and twisted in pain as he died.

Klautz relieved him from his pain. And this was the only way to do so. No healing or miracle could work. He was already beyond repair.

Klautz could save the man by using his Probationer, an item that could cast healing waves. But it would break after one more use. Why should he waste such a precious item on a stranger? It was essential to his survival and he wouldn't use it for others.

The man who died in front of him… Klautz didn't know him. But Klautz felt annoyed… Annoyed at this system set up in Hell that cheers on those who kill their kin.

"It seems he was escaping from something." Klautz whispered.

The man being in the worst state as it can be, it was clear that he was hunted by someone.
