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

"Well doesn't matter," Klautz took his stance wielding the spirit ninjato.

There is a reason why the cloning skill was popular among ninjas. It's good for a sneak attack but that is why it is bad for frontal attacks as well.

"Ha Ha!" Lewis laughed as he tried to gain back his lost confidence. "Surprised? No doubt you are!"

All of the clones charged at them. Klautz had seen many clone users before. Two things are common amongst them.

Firstly the class's effectiveness depends on its rank and quest progress.

Secondly, none of the clone's strength is greater in strength than the original user of the class. This means that all of the clones are no better than those people who don't possess any class at all!

People grow stronger either by defeating monsters thereby gaining stats or by completing class based quests. Someone who doesn't have a single class has odds against him compared to someone who does have them.
