After Alex's discovery of the Cosmic Beasts, he realized he couldn't find all nine members of the Cosmic Force alone. He needed a team of his own. While his team would be smaller than the Cosmic Force or the Chaos Knights, he knew exactly who to pick, though he was unsure where to start.
Suddenly, a woman appeared before him. She claimed to be an assassin searching for him. Alex, taken aback and fearful, asked why she was looking for him. The assassin explained that she and her group had been searching for him because he left without any notice. They didn't want him to vanish like Ben had. Hearing this, Alex clarified that his departure was to stop Ben and prevent the Chaos Knights from being freed. The assassin understood and agreed to help him.
With the first member of his team secured, Alex and the assassin, who introduced herself as Kira, received a mysterious message. The message gave them a clue about the second member of their team. They followed the directions, and to their surprise, they found the second member waiting for them.
His name was Vile. Vile revealed that he knew the location of the first member of the Cosmic Force, adding a crucial piece to their quest.
