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

Benton was clearly a narrow minded 'native fanatic'.Klautz had never met Benton in his previous life… he had never crossed paths. But all the records and testimonials Klautz had received pointed to the exact same thing.

Benton's revolution had most of the powerful groups under his belt. The victory was all but assured. Hell had become even a harsher place for the earth borns who were threatened to either shut down their mouth and accept the terms of 'depravity' or get annihilated. Hell had become a much harsher place for them than it already was.

Yet Benton failed and quite miserably at that.

Klautz smiled seemingly proud of one thing the ninjas had done.

Don't challenge the ninjas
