Lucy has a multifaceted personality that evolves over the course of the series. Initially, she harbors deep feelings of hatred and revenge against ordinary humans due to the mistreatment she experienced as a child. This mistreatment, including being ridiculed for her horns and given offensive nicknames, fuels her intense emotions. As a result, Lucy lacks empathy and kills without remorse, often displaying sadistic tendencies. However, as the series progresses, she begins to show remorse for her actions, especially toward Kohta, a childhood friend who has suffered as a result of her actions. Lucy also develops romantic feelings for Kohta, further complicating her character.


Lucy’s troubled past plays an important role in shaping her character. As a child, she bonded with a dog that was tragically killed by her classmates, triggering her first acts of violence. This traumatic event caused her to lose empathy and develop a deep-seated hatred of humanity. Throughout the series, more details of Lucy’s past are revealed, shedding light on the factors that contributed to her complex personality.


Lucy’s physical appearance is notable for her horns, a distinctive feature of Diclonius individuals. She is depicted as an eighteen-year-old girl with a slender build and long, pink hair. Her eyes, shimmering with a reddish-pink hue, convey a sense of intensity and determination. Lucy’s appearance changes when she switches to her alter ego, Nyu, a childlike and innocent version of herself.


As a Diclonius, Lucy possesses extraordinary abilities that set her apart from ordinary humans. Her most notable power is the ability to create invisible telekinetic arms called “vectors. These vectors, which are invisible to the naked eye, allow her to manipulate objects and attack her enemies from a distance. In addition, Lucy has enhanced physical strength, agility, and regenerative abilities, making her a formidable opponent.


Lucy’s origin is intertwined with the Diclonius species, a fictional race in the Elven Song universe. Diclonius individuals are born with horns and possess telekinetic powers, but are often mistreated and discriminated against because of their differences. Lucy’s experiences as a Diclonius shape her personality and actions throughout the series.
