The world's top assassin had dedicated his life to the organization that raised him until they betrayed and silenced him. Overwhelmed with regret, he sought out a goddess who was amazed by his exceptional talents and offered him a chance to begin anew in a world of swords and magic. His mission was simple yet vital: he had to slay the world's hero to prevent its destruction. Thus, he accepted the goddess' proposal, and Lugh Tuatha Dé was reborn as a member of Alvan Kingdom's noble assassin family. His father trained him in unique assassination techniques, unlike his previous life, and Lugh discovered new abilities and made friends. But he knew he needed to reach perfection to defeat an enemy as immense as the hero, and Lugh was determined to reach it despite the cost.
