Orphaned at the age of ten because her parents were killed by the Blue, Marlene was one of the few lucky ones to make it to Second Earth. Since then, Marlene has dedicated and trained herself to defeat the Blue. Though seeming very heartless and cold in the earlier episodes, as time progresses, Yuji opens up Marlene's emotions and a bond is created. As Marlene's emotions begin to resurface, everything she was taught to believe in begins to break down. Towards the end of the series, she and Yuji conceive a child together.
