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

"Come to think of it… there are no women here, are there?"

Klautz squinted his brows as he finally got tabs on his situation. Watching the men sweat while trying to climb trees, slamming their weapons on boulders and fighting beasts wasn't a pleasant sight at all! Not to mention that Klautz already felt quite conscious when he was in a large crowd irrespective of any gender.

But he shook his head at the next moment. It was simply too embarrassing for him to accept something like that.

"No, I must be delusional. Women are few in number in comparison to men anyway."

This was a phenomena that was only specific to the tutorial zone. The number of men and women were more or less equally matched despite hell being a world of survival. It was all thanks to the satan's system which didn't differentiate between them.

But when it comes to the newbies the same rule didn't apply.
