For centuries, the Amadeus clan was one of the most famous and respected in the entire world. They weren't just the best sword clan user in the world— they were also the guardians of a legendary weapon, the Sword of Blasphemy owned by their ancestors, the Sword Legend Hiryu Amadeus.
This sword was no ordinary blade. It was forged from the scales of the strongest creature in the world, the Dragon and blessed by the God, the Sword Legend Hiryu fought the evil and after years of war, he eliminated and ended the reign of the Demon King, a being so powerful he nearly wiped out 75% of the world. The Sword of Blasphemy became a symbol of hope, the savior of their world.
But behind the power and glory of their family, another evils is waiting in silence. Not everyone is favorable with the authority of the Amadeus clan hold. Within their Palace, the people who they thought were friends, betrayed them and with the help of powerful people who also consumed by jealousy and fear, plotted to bring their downfall and stole the Sword of Blasphemy.
Then, one night, the end of the Amadeus Clan came. The attack was unavoidable and before the leader of the clan knew it, half of the clan were already wiped out. The ambusher were no ordinary fighter— they were cursed beings, who used dark magic. In mere moments, the clan once thought the invincible were slain, and the bloodline that carried the world's hope was wiped out.
But not all was dead. In her final moments, the wife of the clan head transport his son using artifact that have the ability to teleport people. before his teleportation, the child named Hiro Amadeus heard every scream, every clash of falling swords. And as rain started to fall outside the Palace, he witnessed the fall of his entire clan. And in that moment, he felt a cold. Anger and rage consume him—a feeling that would push him to become either the next great hero… or the next nightmare.
Now, the sword of Blasphemy are now in the hands of evils. In the shadows, the followers of the Demon King became active once more, plotting to resurrect their fallen king. But the last survivor of Amadeus won't allow it. His sole purpose remains: to reclaim the sword, revenge to the traitors, and stop the return of the darkness that once nearly destroyed the world.
