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

Klautz couldn't help but remember the time he had spent with Maebi. Wasn't that sex work too?

The only reason that Akihiko had agreed to offer Maebi for a bet was because Maebi wasn't even a ninja in the first place! She was a trainee instead.

Ninjas don't take mission that involve sex work. That's the way they did things.

But what if the client wanted his target to be honey trapped? Who would a client approach then to have his job done? Of course, the lipstick women would be perfect for the job. That is why they complemented the ninjas so well.

"Hell's population keeps increasing due to the tutorial summoning doesn't it? So the people of hell have no incentives to have lovers I guess?" Klautz whispered to himself helplessly, giving an excuse for it.
