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

'It's not like we would be alone,' Klautz thought, twisting his fist.

A huge number of mercenaries under Gozoto's command would always be along with them guarding them. But it wasn't like they would be guarding them against threats or monsters. What would have been the point of grinding if they did that? They would be guarding them against human threats and external instead.

Klautz;s reputation in the group was certainly far greater than Shizu so much so that no one would complain if Klautz were to take over. Indeed, no one would complain except for these mercenaries.

Klautz overriding Shizu's commands and leading the newbies by themselves would be considered a human threat in their dictionary. It would be like a revolt against the strong and influential. And they would be quick to get rid of it.

Klautz doubts that he would be killed the process. But it certainly wouldn't be a good result for him if his trouble only increases more..
