Personaje Principale

* Lucy (ルーシー , Rūshī?) is a teenage diclonius girl around eighteen years old. Lucy has developed strong emotions of hatred and vengeance towards regular humans mainly because of how she was treated by the majority of them as a child, making fun of her horns and giving her insulting nicknames such as freak. She seems to lack empathy, kills without much concern, and acts somewhat sadistically; however, towards the end of the series, she begins to show remorse for her actions—especially towards Kohta.

* Nyu (にゅう, Nyū?) is a split personality of Lucy that developed after a .50 BMG round ricocheted off a metallic helmet encasing her head.[4] Nyu has a childlike personality and infantile knowledge of the world, forgetting even that she is a Diclonius and how to use or manifest her vectors, leaving her as a human with horns. She initially lacks spoken language skills; however, she eventually learns a handful of words and phrases until (in the manga) she can finally speak properly despite the fact she still uses the non-nonsensical phrase nyu as her catchphrase. 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". Whenever Nyu hits her head or when she is confronted with violence, she reverts to her sadistic side, Lucy. Voiced by: Sanae Kobayashi (Japanese), Kira Vincent-Davis (English)

* Kohta (コウタ, Kōta?) is around nineteen years old and enters the story when his cousin's family allows him to move in to their closed-down inn in exchange for maintenance while he goes to a local university. Kohta has repressed traumatic memories of his father's and sister's deaths during his childhood at Lucy's hands. Because of him repressing his memories, Kohta does not remember Lucy from when he met her earlier as a child. Due in part to his loss, he has a soft spot for girls in trouble and is extremely generous and protective to the girls around him. He is more forgiving in the anime, but in the manga when he gets his memories back he truly is unforgiving about Lucy killing his father and sister.

* Yuka (ユカ, Yuka?) is Kohta's cousin. She is also around nineteen years old[citation needed] and attends the same university as Kohta.[citation needed] She last saw Kohta when they were ten, parting ways with him on the same night in which Lucy killed Kohta's family, completely oblivious to the events following their last meeting. She moves in with him at the inn after having not seen him in many years. She has had a crush on Kohta since childhood and this is a topic seen regularly in anime.
