Elfen Lied

The offshore facility, headed by the scientist Kurama, sends a special task force, headed by the ruthless, cold-hearted assassin Bando, to hunt down Lucy at a beach in Kamakura. However, they only encounter her in her innocent "Nyu" state. She is hit over the head by Bando. Bando then tells his partner to finish Nyu off, but the hit reverts Nyu back to Lucy, who kills Bandos partner, and goes after Bando. Lucy uses a firearm to shoot and injure Bando. In the end, Bando has been dismembered and blinded. Lucy reverts to Nyu before she is able to kill Bando. It is seen here that Lucy and Nyu switch between each other depending on the events surrounding them. After being injured by Bando, Kohta is put in the hospital, but is not severely injured, and is released hours later while Yuka goes looking for Lucy. He encounters her back at the house and forgives her.

After alerting the soldiers and Kurama to Lucy’s whereabouts, Nana confronts her and the two begin to fight in a cemetery. Can Nana hold Lucy off long enough for Kurama and the others to arrive? Meanwhile, hearing loud noises in the cemetery, Mayu stumbles upon the two fighting.

Bando escapes from the hospital, still trying to find Lucy to satisfy his grudge against her. Professor Kakuzawa Yūs decapitated body is found by his assistant and Kohta. While searching for Lucy, Kohta and Yuka develop a fondness for each other as displayed through a kiss. Finally, Lucy is found by Kohta and Yuka and taken back home.

After Lucy is knocked out by Nana Kouta tends to her. She sleeps and relives her childhood in a dream, revealing many things about her. Meanwhile, Nana tells Mayu about Lucy and the diclonius and Arakawa is called in to work for Director Kakuzawa...

Lucy and Nana start to fight, but Mayu stops them and Lucy turns back to Nyuu, hugging Kouta and telling him she likes him. Later, Kuramas past is revealed and so is more about the dicloniuses.

Mariko is torturing and playing with Nana like an insect while Kouta runs to her to protect her. Mariko temporally looses her vectors, thanks to Nana, and has to be sent back. Nyuu follows Kouta, but when the soldiers start to shoot at her she turns into Lucy. Seeing the bloodthirsty Lucy, Kouta recalls everything...
