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

The Sun rose above the horizon. The illumination of the rising sunrise flashed across Klautz's eyes. Even that sort of a little bit of stimulus was enough to wake him up. But what greeted him was Selena's smell. Her scalp being just below his nose made her womanly smell invade his nostrils. His hands were still on her breasts.

Klautz didn't get up before giving her breasts another squeeze.

Klautz ignored it as he got up. Today, they are going to face the last boss of the newbie zone so he had to prepare himself. Rubbing a stick against a wooden board he created fire as he tossed branches inside.

He poured water from the Aale into a bamboo container and boiled it onto a fire. Finally, he took out monster meat from the inventory and rinsed it with the boiled water. All the while he had a serious expression on his face.
