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.

Akihiko's laughter didn't cease. There was mockery oozing out of every laugh he made.

'He thinks he can win such a bet? He must be dreaming. Oh, I would love to see his face when he realizes that he has lost.'

"Very well. So be it. You are going to lose in this bet anyway," Akihiko claimed.

Saying so he jumped off the only window to Klautz's quarters.

Klautz sighed as he watched him go. He had no plans to associate with the ninjas. The reason why he proposed the bet was to make Akihiko forget about the idea of recruiting him altogether.

Klautz too knew that he had no way of winning this bet. The purpose of the bet was not to win but to feed Akihiko's inflated ego.

'It would have been a different thing if Akihiko would have sent any random kunoichi. But the chances of that seem to be very low.'
