The Summoned Samurai 3: Dragons Assemble. The Summoned Sumurai, #3

Description: The Summoned Samurai 3: Dragons AssembleThe myths are no longer confined to the shadows. When the absolute entity known as the Black Dragon King personally descends upon the modern metropolis of Tokyo, humanity is brought to its knees by sheer, incomprehensible terror. The sky turns pitch-black, and the city of vacuum is born. To protect his childhood friend Aya from being crushed by this overwhelming mass, Shinji Onishi throws himself into a deadly, supersonic clash against a god-like existence.
Just as his life is about to be extinguished, a miraculous light tears through the darkness. Breaking a 400-year seal, the Silver Dragon-Oshin-finally awakens to fight by her son's side, unleashing a torrent of power that shakes the very foundation of the world. Meanwhile, across the Pacific, an immortal warrior with dragon's blood feels the tremors of this colossal battle. Siegfried, a man who once crossed blades with the legendary sword demon Genzo in the feudal era, senses a phenomenon that reignites his long-lost warrior's spirit.
Guided by an irresistible telepathic call, he leaves his hollow life behind and boards a flight to the Far East. The King has fallen. The Silver Dragon has returned. And the immortal veteran has arrived at the Tendo estate. The actors are assembled. The ultimate convergence of warriors, dragons, and myths is about to begin. Welcome to the new world.
