A work from the remake series of the classic anime "Space Battleship Yamato," this is Chapter 3 of the full 7-chapter (26-episode) series "Yamato, Forever REBEL3199," which reinterprets and reconstructs the third theatrical film released in 1980, "Yamato, Forever." 　On Earth, now absent of the Space Battleship Yamato, a peculiar daily life has begun where the Dezarium, who have settled based on the Earth occupation plan, coexist with the ordinary people. At the elementary school attended by Tsubasa, the son of the fallen Saburo Kato, a Dezarium girl named Fleur transfers in. The Dezarium gradually blend into their surroundings, and Earth's people begin to accept them. Amidst this, partisans centered around former Yamato fleet crew members plan a large-scale resistance operation to expose the true nature of the Dezarium to the world. Meanwhile, the Space Battleship Yamato attempts to break through the pursuit of the invisible battleship Grodaze and enter the Garmillas star system.
