Amata, still worried about whether or not Mikono will forgive him, meets a talented student with a strong Element power named Shrade. Meanwhile, a new attack on Vega is set into motion, and Amata, Cayenne and Andy are called into action.

While mourning the lost lives, students at the academy begin to realize that they’re fighting a life-or-death battle. In order to face the battle against Altair, which is expected to further intensify, Fudo assigns the students a new training.

While digging a hole, Andy finds an ancient book and thinks that it is the legendary book called “The Book of the Twin Stars.” In the meantime, Jin gets on board the heavily armored Radius Gnis in order to mount another attack on Vega.

After heading to Vega once again, Kagura finally finds Mikono and tries to kidnap her. When Amata takes Mikono and runs, Kagura further pursues her in Mithra Gnis. This time, Cayenne, Zessica and Andy are ordered to fight the Abductor.

Mix has been taken to Altair. While Andy is feeling down for not being able to do anything as the dimensional gate is closed, Zessica is also suffering a guilty conscious for what happened to Mix. Then, Mykage suddenly shows up in her dorm room.

The excessive use of the dimensional gate has caused Altair’s energy supplies to dwindle. Feeling that Altair is at the end of its rope, Izumo decides that he, himself, will head to Vega this time to bring back Rare Iguras.

Although Amata and the others were able to come back from Altair safely, their mission to retrieve Mix ended in failure. While Andy deals with the frustration of not being able to get Mix back, Amata decides to go find Mikono.

Andy escapes from captivity and continues to look for Mix. Outside the building, Yunoha and Zessica’s condition is deteriorating for some unknown reason. In the meantime, Amata encounters Altair’s leader in the mysterious room he found his mother.

When Amata goes back to where he first met Mikono to look for her, an Abductor appears. Shrade, Cayenne and Sazanka are deployed to fight it. In the meantime, Kagura shows up and he and Amata fight as Mikono begs them to stop.

Following Kagura and Mikono, Amata, Zessica and Shrade enter the dimensional gate. However, they become adrift in the dimensional gap. Meanwhile, Fudo and Crea explain the myth passed down for twenty-four thousand years.

The Mythic Aquarion finally awakens in response to Kagura’s call. Boarding the Mythic Aquarion along with Mikono and Zessica, Kagura pilots the Mythic Aquarion and fights Izumo and Mix in order to keep them from taking Mikono away from him.

Jin contacts Altair to let them know he is still alive. Izumo orders him to infiltrate Neo-DEAVA to search for a Rare Igler who can be the true Eve and also to attempt to retrieve all or part of the Mechanical Angel.

Fudo assigns a top-secret mission to the Elements but gives them no details about their mission. While the Elements await the details of their mission, Andy summons the courage to tell Mix how he feels about her.

Andy says that holes are his very life. Mix states that she hates holes. In training, they’re required to merge but refuse to do so. Despite the fact that their Gattai didn’t go well during training, Fudo sends them in to a real battle.

Mikono is told that she is prohibited from leaving her dorm as punishment for defending Kagura. Alone in her room, she herself wonders why she defended him. In the meantime, Fudo proposes a new training... a real combat training between Aquarions.

Still feeling the barrier between the guys and girls even after the academy became co-ed, Andy suggests changing the seating arrangements in the classroom. When he didn’t get the arrangements he hoped, he starts talking about an Element who disappeared.
