Serious Problems: Split personality where one is a mass murderer and the other is a kiddish, innocent, caring person.
Personality: Lucy (ルーシー , Rūshī?) is a teenage diclonius girl around 18 years old, Lucy has four vectors with a limited range of two meters.[3] However, she can be swift and lethal within that range, and will use any nearby objects as high velocity projectiles to kill at greater distances. She is also capable of stopping or deflecting most standard ammunition when she concentrates on the task. Lucy hates humans mainly because of how she was treated by her human peers as a child. Consequently, she discounts non-diclonii, claiming they are not real people, to the point of telling Nana that she has "not killed anyone yet". She seems to lack empathy, kills without much concern, and acts somewhat sadistically. Despite this lack of concern for human life she will not harm Kohta, crying and apologizing for killing his family. She refrains from killing in his presence, except at the end when she kills a whole army in front of him, which reminds him of his suppressed trauma.
Nyu (にゅう?) is a split personality of Lucy that developed after an .50 BMG round ricocheted off a metallic helmet encasing her head. Nyu has a childlike personality and infantile knowledge of the world, and lacks spoken language skills, only able to say "Nyu" and "Kohta" most of the time. Near the end of the anime, she develops a wider vocabulary, being able to say phrases like "Don't cry, Kohta!". Nyu is innocent and incapable of violent acts, a foil to the normally cold and sadistic Lucy; she is the manifestation of her "good side". When Nyu is attacked violently (or hit on the head), she regresses into Lucy; likewise, when Lucy is treated with love and kindness, or wants to hide herself from Kohta, she will uncontrollably switch back into Nyu. While Nyu exists first due to trauma, it is believed that Lucy subconsciously encourages her presence due to her feelings of guilt towards Kohta and to prevent her from harming him (directly or indirectly). In the manga, this is confirmed by Lucy herself
