Lucy/Nyu
Lucy/Nyu is a Diclonius girl around eighteen. Lucy has developed strong emotions of hatred and vengeance towards human beings mainly because of how she was treated by the majority of them as a child; they made fun of her horns and gave her insulting nicknames such as "Freak." As a child, she bonded with a dog which was killed right in front of her by classmates, which triggered her first killing. She seems to lack empathy, kills without much concern, and acts somewhat sadistically, often torturing victims before killing (such as Bandou and Nana, although she did not actually kill them); however, towards the end of the series, she begins to show remorse for her actions, especially towards Kohta, whose father and sister she killed.
