In front of the prison Hanji remembers the events of two years ago. Back then, Historia welcomed the Asians on the island after the port was finished. The head Kiyomi turned out to be of the same race as Mikasa and Mikasa turned out to be the descent of the almighty Shogun.
Kiyomi has the following plan for the eldians.
1 .Prove the world that Eren Yeager is a god of destruction and he can turn the world upside down with the titans in the walls.
2. Increase the island military power to equal the rest of the world.
3. Obtain Zeke's "Beast Titan" by feeding it to one who has royal blood... And have as many royal children as possible.
Historia accepts to inherit the Beast titan either by herself or her children, Eren is mad at that.
Eren wonder in the present what has happened to Historia. He tells Hanji that it's useless to put him into a prison due to his evolved titan powers. He grabs Hanji in fury, but the later leaves saying eren is still a teen. After leaving the room, hanji says that Erwin shouldn't have made her succeed him.
Historia is elsewhere. Pregnant.
