Truck-kun's deadly embrace redirects Owen from his fated confession to the woman of his dreams. Instead of eternal rest, he awakens reborn—a golden dragon egg hatching beneath dungeon stone, only to be discovered and tamed by that very same milf, Yuki Goldberg, an F-Rank beast tamer. His new body harbors unimaginable power: an SSS-Rank dragon consciousness intertwined with The Dragon King's Bloodline. Ancient sovereignties awaken within him—dominion over Destruction, Space, and Time itself. Dragon's Eye, Breath, Aura, and Tongue manifest as SS-Grade abilities, complemented by miraculous Ultra-Regeneration. Where Owen once dreamed of simple pleasures with his master, reality demands otherwise. Yuki faces siege from all sides: ambitious factions hunting her stolen strength, realm-destabilizing dungeons spawning monstrosities, were-beasts and demons plotting humanity's extinction. As her tamed beast and secret protector, Owen transforms from lovesick dragon to formidable guardian. Between managing overwhelming abilities and thwarting apocalyptic threats, Owen's journey proves far more complex than fantasies once promised. His obsidian scales—born from golden potential—become instruments of devastation as he defends Yuki from annihilation, all while grappling with a power too immense to control.
