Godzilla has went through a mysterious portal that sends him back in time and gives him the ability to talk. He ends up back in the year 845 where he meets Eren Yeager, Armin Arlet and Mikasa Ackerman. Later on, he discovers that his old allies, Mothra and Rodan, have also ended up here. Now, it's up to them to save humanity, and wipe out every last titan that stands in their way. Or do they need to worry about something lurking among the stars.
