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

Saying so, Gozoto left the room. But even he knew that 'hope' was but a four letter word.[1]

Klautz too came out of his hiding. He had made an easy entry in the room and the information was laid out for him on the table. But it was taking him longer than he expected.

With no proper equipment, he had to note down the names and data of every murdered individual for he can't really take the register with him and leave behind any clues.

By the time Gozoto arrived, he could only note down half the data.

"There doesn't seem to be any other information other than the newbies that have died."

Klautz sighed. His suspicions were right. The killer had some way to bypass leaving any clues. So many deaths and not a single clue left.

"Once or twice was understandable but so many times?"
