Nero 66 arc

The **Nero 66 arc** is the thirteenth story arc of the Edens Zero series and the last arc in the Aoi Cosmos Saga.

The Interstellar Union Army engages in battle with the Imperial Army in space, allowing the Crew of Edens, accompanied by the rebel army Oasis, to advance towards Nero 66, the Planet of Ash. Their goal is to destroy the All-Link System and take down Poseidon Shura before he can use the network to destroy every machine in the Aoi Cosmos! To succeed, they must prevail over Shura, the self-proclaimed "King of Gravity", as well as the most powerful soldiers in the Empire, the Oceans 6! As the high tide approaches, the fate of the Cosmos hinges on this battle, which may prove to be too much for the Crew to handle!
