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.

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.

During Touma's next attack, he exposes to the other elements the truth about Silvia and Sirius' origins. Taking advantage of their shock over his revelation, Touma manages to convince Sirius to abandon his friends and join the Shadow Angels' side.
