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

"Guy get me out of here!" the man stuck in the worm's teeth shouted.

"Yeah, as soon as I get rid of this pest," his friend said as he swung his axe towards the man-sized worm. A frown was visible on his face. He was already having quite a bit of trouble with the one he was dealing with so much so that it wouldn't be an understatement to say that he was putting his life on the line.

Not only him, but all of his friends were also struggling against the so-called small worms. They were small only in comparison to the death-worm while in reality they were man-sized.

'It's the same' That was the only thought that came to Klautz mind.  The scene in front of him was strikingly similar to the time he had fought with this beast in his previous life. Even then the beast had swallowed a woman alive.
