Marianne Louvre is the 15-year-old daughter of Professor Charles Louvre, is of French nationality and is the engineer who led the construction of the "Bismarck". A computer genius, Marianne was the chief envoy from the colonies to Earth. When the Deathcula attack, she calls on the colonies to join the EFG. During this meeting between the colony leaders, Marianne is chosen to join the "Bismarck" team, much to the pleasure of her father. Marianne is very technically minded, and most often helps her teammates from her station aboard the Bismarck. A brave girl, she's normally quite repulsed with the idea of killing anyone, even Deathcula. Marianne and Shinji have known each other since childhood, and soon become romantically involved.
