Intro
One day, Guest was attacked by a monster and injured. Though the wound itself was minor, Jade turned pale upon seeing it. Soon, a simmering rage took hold of him, and he spoke with cold, dead eyes.
With that, Jade stormed out of the house. He pulled the Holy Sword through sheer grit, became the Hero in an instant, and vanquished the Demon King in less than a year.
Ignoring the victory parades, Jade rushed straight back home. He brought his traveling companions with him.
