فصل 1

Pierre Vieira and Silvia de Alisia are out on a mission in Arc City to find the reincarnation of the "Solar Wing", and their current target is an orphan named Apollo. However, Shadow Angels suddenly attack the town, and DEAVA sends out a Vector unit consisting of Sirius de Alisia, Glen Anderson and Hong Lihua to deal with the threat.

After the battle, Apollo has been put into detention until DEAVA can find out more about him. Meanwhile, Sirius, Raika and Silvia head out to battle more Shadow Angels, but trouble arises as yet another Cherubim arrives. It is revealed though, that these Angels are but mere soldiers, as this one is controlled by a human-like Shadow Angel known as Toma. What's more, Toma has a connection to Apollo's previous life...

Apollo enters the Element school, where the Elements train. The new recruits - Apollo, Jun Lee and Tsugumi Rosenmeier - then enter a training simulator, and Apollo ends up being partnered with Silvia. In the simulator, the two accidentally shares a kiss. Later on, the Shadow Angels appear yet again, and Silvia, Sirius and Raika heads out to attack them. However, Apollo accidentally winds up in Silvia's Vector, and now they need to co-operate to fight properly.

At a meeting of Shadow Angels, Toma reveals his plan of creating a new world with the help of the Solar Wing. Elsewhere, at the Element school, the Elements do an exercise which includes being barefoot. Later on, when a gravity-canceling Shadow Angel attack, their exercise proves to be very helpful.

Apollo wants to search for Baron, and goes missing trying to look for the Vectors. This leads the Commander to initiate a special exercise for the other Elements: Find Apollo. What they doesn't know is that the exercise has a special meaning, which is to work together as a team. When Shadow Angels attack later on, Apollo, Silvia and Pierre manage to learn this lesson, and they beat the Mythological Beast which has appeared.

Jun and Tsugumi are both worried about their first unification, and ask Pierre and Reika respectively about it. Tsugumi however, is very hesitating when it comes to going on a mission because of her powers. Later, when a new kind of Kelbim soldier appears, Jun, Apollo and Pierre are sent out to stop it; Pierre replacing a hesitating Tsugumi.

The Mythological Beast Titania has appeared, and it abducts children in their dreams, causing them to never wake up again. Most of the Elements also gets caught, but some of them wake up again, and they need to find a way to fight this Mythological Beast.
