Enjoy The Four Pillars, The Culling, and The Riven Mother together in one mighty collection representing the first season of the Realm of Goryo Series. By the year 2061, Goryo, the kaiju-king, and dozens of more kaiju have overrun Japan and the only thing holding back total annihilation is the Mighty Tengi, the kaiju-mother. An uneasy alliance has been made between humankind and Tengi, but the truce is only building a powder keg ready to explode. An amphibious species in the Pacific Ocean, the caudatas, are ready to return to the surface with their kaiju-god, Lord Tatsumi, leading the charge. Proving to be a new megapower on the world, humankind must rally to survive against the new threat. Now, it is up the UN's kaiju defense forces, Tengi, Goryo, and others to stop the threats that Lord Tatsumi's destructive force ushers in, including the Riven Mother, Raisha.
