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

Everyone watched at the stadium with wide eyes. There was a complicated expression on their face that switched from frown to anguish from time to time and sometimes to plain fear.

If Benton was like the predatory bird who threatened soft bodied caterpillars like themselves, making them want to quickly morph into a butterfly and fly away.

Then Colt was the predator who just played with them as if they were mere ants. Or so was the case with the challenger.

His face was swollen red, making his previous glory self completely unnoticeable. The knightly armor was in tatters and his face barely represented his actual self.

On the other hand, the second gen who hadn't proved to be a threat to any of the newbies yet clicked their tongues in remorse. There was nothing they could do now. They could only bite their nails and lament at their loss.
