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

"Looking at the situation, it is time for them to come."

Klautz squeezed his eyes shut trying to catch breath among the horde of a crowd. Being alone throughout his previous life, he found himself a little uncomfortable when suddenly forced into a juttering crowd.

Within a day, the number of mercenaries working at the newbie camp had become thrice of its initial number. It was hard for Klautz to discern the number of ninjas who were working in the shadows but he believed that it had its own substantial growth as well.
