Elfen Lied

Lucy is a special breed of human referred to as "Diclonius," born with a short pair of horns and invisible telekinetic hands that lands her as a victim of inhumane scientific experimentation by the government. However, once circumstances present her an opportunity to escape, Lucy, corrupted by the confinement and torture, unleashes a torrent of bloodshed as she escapes her captors. During her breakout, she receives a crippling head injury that leaves her with a split personality: someone with the mentality of a harmless child possessing limited speech capacity. In this state of instability, she stumbles upon two college students, Kouta and his cousin Yuka, who unknowingly take an injured fugitive into their care, unaware of her murderous tendencies. This act of kindness will change their lives, as they soon find themselves dragged into the shadowy world of government secrecy and conspiracy. The "diclonii" (singular: "diclonius"), otherwise known as a two-horned human, are mutants of the human species, may well be the next step in human evolution. The diclonii have horns and strong telekinetic powers represented by arms. However with this great power, they could easily destroy the human race. Fearful of their power, humans quarantined the diclonii into secret research facilities to study.
