After Shun successfully leads the Resistance into Alpha City, Mira departs on her own mission: searching for her older brother, Keith. She heads to her home to search for clues on her brother's computer but comes up with nothing. After her father, Prof. Clay, arrives, she confronts him and he simply says that "he is no more." When she further questions him, he leaves for his lab, while Mira follows. Meanwhile, Shun takes the others to check out the control spire and they learn that the battles that take place in the arena below the controller are synchronized with the controller's power.
