The Other Side of the Sea

Four years after the Warrior Unit's defeat on Paradis Island, Marley is at war against the Mid-East Allied Forces. As a result, the operation to reclaim the Founding Titan was put on hold. In the final battle at the Allied Forces' base, Fort Slava, Marley sends Eldian soldiers, including child Warrior Candidates (candidates to inherit the power of the Nine Titans after the current ones 13-year term is up) Falco Grice, his older brother Colt, Reiner's cousin Gabi Braun, Udo, and Zofia. The Allied Forces' armored train contains a deadly anti-Titan cannon. Gabi manages to disable the train with hand grenades. This allows Pieck's Cart Titan and Galliard's Jaw Titan to attack. From an airship, Eldians are transformed into Pure Titans by Zeke using his scream, and they, with Reiner's Armored Titan, destroy the fort. Zeke's Beast Titan annihilates the Mid-East Allied Fleet, ending the four-year war with Marley victorious. However, after witnessing the improved anti-Titan weaponry other nations are developing to combat them, Marley realizes they must resume the operation to retrieve the Founding Titan.
