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

"Tch," Klaytz couldn't help but click his tongue as he pulled out his sword stuck at his collar bone. Blood gushed out of the poor boy's shoulder but he didn't care as he pushed the boy in annoyance. Why won't he? He was so close to killing the girl yet he failed...

Klautz had a policy of not killing the innocent. In the past life he had killed many innocent in his work as a ninja. He doesn't want to walk on that very same dark path again. If it were the old Klautz he would have eliminated all potential nuisances like this before moving onto the main battle. But in this life no innocent was harmed to his blade.

"Ow!" The boy squealed as he fell onto his butt. That was when he felt Klautz's chilling blade on his neck.
