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.

Benton sighed with his own worries weighing his shoulders.

"Master, this is the eight newbie camp since the year it was established," Benton paused as he heaved a sigh, "And also the eight years since the day you left me," Benton continued with his soliloquy, "Yet your goals have still never come to fruition.

Such an intense and dog eat dog world was indeed too much for a human child to bear.
