In the western fantasy world called "Athel", the human kingdom coexists with various monsters. The rural village of Dole on the edge of the continent seems peaceful, but in fact, the threat of low-level monsters such as goblins lurks. The protagonist Ryan was originally an ordinary boy. Due to an accident, he obtained the "Demon-Slaying Eye" - the mysterious ability to see the weaknesses of monsters and absorb their energy. From then on, he embarked on a journey to kill monsters, upgrade and become stronger. In the darkness of the world, the mysterious organization "The Church of Shadow" is planning to resurrect the ancient evil god, and Ryan's rise will change everything.
