One day, a mysterious gate tears open in the heavens, unleashing a catastrophic invasion of monsters upon the human world. As humanity struggles to survive the sudden onslaught, monks from beyond the veil intervene, stepping into the mortal realm to confront the unprecedented threat. Amidst this chaos, Han-Yul relies on an unconventional method to fight back, treating his combat preparation like a precise medical procedure. His secret weapon is a so-called miracle drug known as coffee. Carefully administered, its medicinal contents—caffeine and sugar—work together to provide an immediate surge of energy while aggressively stimulating his central nervous system. This potent combination maximizes his senses and reflexes to their absolute limits, granting him a critical edge against the monstrous invaders. As the compound takes full effect, the world around Han-Yul appears to slow down to a crawl. Time itself seems to stretch as his heightened perception kicks in, allowing him to move with devastating speed and precision. In this altered state, his medication finally reveals its true power, transforming him into a formidable force capable of standing against the otherworldly horrors pouring through the heavenly gate.
