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

Everything was dark. Visibility was zero.

Bill could not locate his friends. Only his sense of touch and hearing to his help. He couldn't make out their forms as if he had lost his eyesight. And not only Bill but all of them were in the same state.

An unknown smell drifted in his nose.  It smelled like roses but was a little different.

The guy who was walking in his rear fell to the floor as he became unconscious. Bill eyebrows rose high so much that his forehead disappeared.

"Everyone covers your nose! Don't breathe in this air!" Bill shouted at the top of his voice as he covered his nose and his voice.

But it was too late, as he heard no sound from behind him. It was all a deathly nothingness. He was with a group of nine but everyone had become dead silent.
