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

A yellow ball of light appeared in front of everybody's status screen. Little by little, it grew into a sparkling light as it grew more and more and swallowed the participants of the trial.

They all disappeared from the room, leaving the otherwise distinctive black room empty.

It was such an irony that the room was considered distinctive by them cause it had nothing in it. Just plain black walls which were now cracked after the battle.

But that is human nature it considers everything which it doesn't know about as distinctive. It fears the unknown.

And the only one in this world who had conquered the fear of the unknown was Klautz. Being reborn from the future he was the only one who knew the fate of humanity and the war that was to happen between the humans and the demons.
