Once all people received Souls and incredible powers. Some were lucky enough to obtain the Soul of an ancient and powerful creature, but fate was not favorable to all. The world began to change, and creatures evolved. But, it was not the beginning of a new era. It was the end. A couple of months later, a dark mist appeared and destroyed the world. It was a dictate of destiny from which no one could escape. Wain Norheim was the world's best assassin and the only one who didn't get a soul. However, he was destined to gain the power to confront fate. Escaping through a portal into another world, he unknowingly began the apocalypse. Even the world failed to expel him.
Titles were a unique power that was very difficult to obtain. Sometimes they were simple, but sometimes they were very complicated. Some titles could be activated at will, like some skill. But, to activate the effects of many titles, certain actions had to be performed.
During the battle with Forgotten, Wain realized that he lacked skill in swordsmanship. He could win by relying on good equipment and stats. But that would not be the victory Wain desired.
He preferred getting rid of his weaknesses rather than pretending they didn't exist. Of course, it was impossible to get rid of all weaknesses, but that didn't mean Wain shouldn't try to do it.
Wain wanted to get better at swordsmanship, so his concentration reached its maximum. At the exact moment, his title, which he had gained after defeating the head of the Samurai robots, was activated.
