I finally remembered it all." Kidd muttered to himself after recovering his memory. A young man who lost his memory earlier wakes up in a changing Western town, but the gears of fate started turning thousands of years ago. A continent intertwined with magic, the gentleness buried by the Holy Spirit. The mysterious oriental martial arts, the dragon soul awakening in the monument. The former sword master once said of the young man: "He is a being that can destroy everything, but he is also the only dawn in this world." Drink with the Beast King, fly with the giant dragon, dance with the demons, take revenge with the Holy Spirit, confront the Demon God, and mediate with the Void Lord. Young Kidd wakes up after a thousand years and finally begins the era that should have belonged to him!
