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

"Colt Ackerman, huh?" Klautz whispered as his gaze travelled across the name.

Klautz doesn't remember him to be an influential figure. He had achieved some success in his earlier youth life but after he grew into an adult his achievements were overshadowed by his peers, until he ended up being a drunkard in self remorse. He was a failure in every way.

But that didn't stop Klautz from knitting his brows,

What was weird about his name being here was that Colt Ackerman had never had any connections with the ninja organizations. He had nothing to do with either side of the coin.

That is when Klautz recalled something.

"Wait, Colt Acherman! Shouldn't he be among the second gen this time around?"

One of the key factors regarding Klautz's past life was that he his immaturity during his early years in hell. As such he hadn't paid much attention to the identity of the second gen that had participated with him in the newbie drill.
