While Cliff, a 27 year old young man, was visiting his grandparents, he was caught in what is called a "summoning" which took him to a forest infested with unknown creatures, he decided that in order to survive, he should be ready to brave all the dangers that would present to him, with his “drain” skill he would fight them to become stronger
Cliff stood firmly on the steep slope of the roof, his thoughts swirling like the snow that whipped around him. The icy breath of the wind bit at his skin, but he paid little attention to the cold. His gaze was fixed on the swarm of creatures below, roaming freely through the deserted streets of Freiden. There was something hypnotic, almost surreal, about the scene. The sheer number of "variant" class monsters wandering the village as if they were its uncontested rulers was staggering.
