Lucy is the protagonist and anti-hero of Elfen Lied. She is the Queen Diclonius, an evolutionary offshoot of the human race. She is also the love interest of the secondary protagonist, Kouta.
Lucy, which is her normal and original self is calm, neutral, and peaceful to herself, always wanting to blend in with society especially the human world, she shows a more gentle side towards her love for animals and cares for them until they can move forward on their own to survive into this dark and cruel world she lives in. When Lucy is Nyu, she is more joyful and enthusiastic towards everyone as long as they don't cause her pain and suffering in her life.
