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

The different specialized groups under the Yukiho banner worked all that at the same time. While the Collectors collected the horns, the supporters tended to the injured, All the while the hunters fought with the current beast in front of them. Not to mention the scouts had already begun searching for the next Dreadtar even before the current Dreadtar was killed.

Klautz had indeed built the perfect coordination considering their earlier lack of expertise in anything among the newbies. Most of the skills they had to their name were but irrelevant in the world of hell.

But the cost of learning these new skills was possibly higher than they could have every imagined but the newbies won't be realizing it anytime soon.

"Klautz, which group are we sabotaging first?" Evelyn asked Klautz.

First Target
