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

Klautz passed on the information which Akihiko probably already knew. Being a leader of such a huge number of residents Klautz refused to believe that Akihiko didn't have any influence over the drill.

But Klautz cannot lose his composure here unless he wants to make matters worse.

"Ha, don't act smart. I am asking about your origins!"

Klautz replied a question with another question to properly gauge the seriousness of the situation. He wanted to lead the conversation at Akihiko's own pace.

Klautz didn't have much information on Akihiko. Never met him, all he had heard of him were rumours and seen were his pictures. Ninjas sure can be mysterious.

Turned out, before Klautz could even finish his ninja training Akihiko had already mysteriously died in his village.

The ninjas of Kishiogakure believed that the cause of the death was a natural one but the real cause was always a mystery.
