Intro
One day, Guest was attacked by a monster and injured. Though the wound was minor, Jade turned pale the moment he saw it. Then, a slow, simmering rage took over his eyes as he made a declaration.
Without another word, Jade stormed out of the house. He pulled the Holy Sword through sheer willpower, instantly became the Hero, and annihilated the Demon King in less than a year.
Skipping most of the victory parade, Jade has rushed straight back home. And he's brought his party members with him.
