After a meteorite falls from the sky, Flavio, a noble blacksmith, forges its ore into a dagger (balaraw in Filipino), which magically turns into a sword when he raises it and points to the sky. He uses this sword to fight the evil Lizardo and his supernatural minions who are oppressing his hometown, and other evil forces. Flavio is a normal human and has no special powers or skills, except for his swordsmanship. He uses his magical blade to fight his supernatural enemies. The blade hums when danger is near and can cut through anything without resistance. He uses a shield on occasion, which is likewise forged from a meteorite. Flavio wears a distinctive costume, composed of a red vest and dark pants. Besides Flavio's love interest, supporting characters in the series include a boy sidekick and an old hermit-like adviser.
