Just when the students at St. Angel Academy have completed their Grave Training, Kagura, who was sent to Vega by Mykage, shows up before them. Realizing that Kagura is after Mikono, the students try to help her escape.

While the Element candidates are prohibited from being in a romantic relationship, they are divided into mixed-gender, three-person groups in their field trip. This activity is part of their training, but what is the purpose of this strange arrangement?

Although both Amata and Mikono are brought to the St. Angel Academy in Neo-DEAVA, they’re on different sides of the Berlin Wall and cannot see each other. So Amata decides to work with Andy in order to be able to see Mikono again.

A dark Aquarion controlled by Mykage has appeared in front of Amata and the others. In order to stop the two planets and all life from being destroyed, Amata and the others must defeat the dark version of Solar Wing.

12,000 years after the battles fought by Aquarion, machines from another dimension called Abductors begin attacking the Earth and kidnapping people. Two Aquarias protect humanity from the Abductors, but then a more powerful enemy appears...

During the fight, Cayenne’s element power, Despair Prediction, shows another vision of the wedding in mourning clothes. This time, he sees the faces of the bride and groom. What’s the meaning of this vision? What does it mean to the bride and groom?

After his parents die as a result of Kagura’s attack, Amata becomes furious at Kagura, his other half, and attacks him using an incomplete form of Aquarion. Meanwhile, Andy continues to try hard to get Mix’s memory back.

Mayhem follows Onishi as Organo loses faith in his power as a leader. A messenger delivers a warning that investigations from above the city have begun. When Onishi returns home, it is evident that there is little room for wrong moves or carelessness.

The level of violence rises after an unidentified arson sets fire to Alliance headquarters. Shinji and his Rakan thugs interrupt Onishi’s attempt to negotiate with the leader of Alliance—inciting a bloody war on the streets.

Attempting to take over Organo, one of Onishi’s former allies fails to make an impression on the Rakan and the Union. Ichise joins in a hunt for a man responsible for the recent bombing to clear Onishi’s name and stop the swine trying to take his place.

The struggle for control of Lux continues. Two factions plan to take advantage of the other’s recent weaknesses, but the outsider orchestrating the mayhem reveals his motives to Shinji. Then, Onishi finally faces the antagonist in a deadly showdown.

Onishi visits the Elder of Gabe for advice and receives a message from the Seer about his future. When she tells Ichise her visions of his future, he swears that he won’t allow it.

After joining Organo, Ichise starts working with Toyama. Ran is wandering the streets alone when he sees her, and she is soon consumed by visions of his future.

Reports of several men going missing include sightings of a ghost-like figure at every scene. Deceit runs rampant within Organo, and Ichise is roped into a murderous scheme. Meanwhile, a member from the Class pays Onishi a visit.

Violence still taints the territories of Lux. Doc calls Ichise in to repair his hand—and to use him as her key to escape the city and return home. When things don’t go quite as planned, Ichise’s killing instinct takes over.

The Class spares no one in the slaughter to “clean” the streets of Lux. Every man now fights desperately to survive, regardless of their former ties. Hal returns to show off his new strength and settle his score with Shinji.
