Elfen Lied - Season 1 - Eps 2: Annihilation
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 Bando's 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.

Synopsis
The Diclonius, a mutated homo sapien that is said to be selected by God and will eventually become the destruction of mankind, possesses two horns in their heads, and has a "sixth sense" which gives it telekinetic abilities. Due to this dangerous power, they have been captured and isolated in laboratories by the government. Lucy, a young and psychotic Diclonius, manages to break free of her confines and brutally murder most of the guards in the laboratory, only to get shot in the head as she makes her escape. She survives and manages to drift along to a beach, where two teenagers named Kouta and Yuka discovers her. Having lost her memories, she was named after the only thing that she can now say, "Nyuu," and the two allow her to stay at Kouta's home. However, it appears that the evil "Lucy" is not dead just yet...
