Traveling across a different world with two phantom beasts, Randy, the orphan of the Thunder Shadow clan, holding a silver comb in his hand, struggled to survive amidst the machinations of the aristocracy and the conspiracy of the church. When the black mist of the Holy Skeleton Potion enveloped the continent, he used elemental resonance to awaken the bloodline of the phantom beasts, and embarked on the road of revenge with the lightning tabby cat Ash and the flame cub Gray. From the black market of the royal capital to the Forest of Thunder Shadow, the triple identity cards stirred up the storm, and the seven series of magic tore apart the false mask. See how the descendant of the Beast Taming King uses the phantom beast as a blade to uncover the truth about the curse of the stigmata, and recast the glorious poem of the Thunder Shadow clan within the bonds of blood and contract!
