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.
It took Wain about two hours to reach the ninety-seventh floor. Wain expected that he would meet someone very strong before he reached the very top. As the difficulty increased smoothly from the first floor to the last, this made sense.
'This pagoda is one big challenge made up of small stages. Spirit Knight was a serious opponent. Maybe now I'll meet someone even stronger.' Thought Wain climbing up to the ninety-seventh floor.
Suddenly Wain felt an eerie aura and coldness coming from there. He took a step forward and saw his next opponent. It was an anthropomorphic, large creature. It had bright, red skin and a large head with no eyes but a huge jaw.
The monster was greedily devouring someone at that moment, and it was not a man or another monster. This creature was devouring a large, white soul. It was a soul eater, and this was not its first victim.
