In an alternate history where the male population is nearly decimated, eligible men serve as concubines to the woman shogun inside the walls of the Ooku.

A high school student discovers he is an Ajin, a demi-human being. He ends up a fugitive on the run because of his powers.

Humanity's desperate battle to reclaim the Earth from Godzilla continues. The key to defeating the King of the Monsters may be Mechagodzilla, a robotic weapon thought to have been lost nearly 20,000 years ago.

Years into the future and the human race has been defeated several times by the new ruling force of the planet: "kaijus". And the ruler of that force is Godzilla, The King of the Monsters. Humanity is in such defeat, plans to leave the planet have been made, and several people have been chosen to look at a new planet to see if it is inhabitable. Realizing it's not, though, the human race resorts to plan B: to defeat Godzilla and take back their planet.

Humanity, their alien allies, and Godzilla all enter their endgame as the powerful destructive entity known as Ghidorah arrives on Earth.
