If you liked the Armitage III anime, the Anime-Planet community thinks you'd like:
Murao Mima has created a robot daughter named Key, but after raising her for a very short time, Mima dies, leaving behind cryptic messages telling Key how she can become human. Key must struggle alone to learn the harsh lessons of life and search for the 'key' to her own dream: the power of 30,000 friends to make her a real human girl.
While Key is very, very old looking and Armitage is gorgeous, both are very dark and cyberpunk (Armitage moreso than Key) and both completely kick ass. If you liked either Key or Armitage, you'll surely like the other.
She cooks, she cleans, and is a lethal fighting machine. Mahoromatic, former Vesper battle android, has chosen to give up her weapons, extending her remaining life from 37 to 398 days. As Misato Suguru's maid, she fights battles of another sort, fending off an amorous teacher on one hand, ecchi magazines on the other. Can Mahoro save Suguru's innocence?
Some years into the future, a strange, unexplainable natural disaster has broken off a piece of the Japanese mainland. Known as the Lost Ground, it is now inhabited by people with Alters -- machine-like extensions of their own will. In order to keep the peace on the Lost Ground, the HOLY organization uses its own Alter capabilists to police the region. In the midst of the chaos is a young man named Kazuma, whose life will soon change forever as he discovers his hidden abilities, and how to wield them.
Both anime take place in a similar dystopian future, and deal with racism, to some extent. In S-Cry-Ed those born with special powers are hated and feared, and in Armitage III it is the same, but with cyborgs. S-Cry-Ed has more of a cheesy, yet enjoyable, superpower approach to this while Armitage III handles it in a much more mature way.
Thousands of years in the future, the world is overrun by demons and vampire lords. Doris, a young girl, has become the target of the great vampire lord Count Magnus Lee, who wants her as his plaything. After being bitten by the Count, she seeks the help of D, an elite vampire hunter, who decides he must venture out to slay the Count and his demon underlings to save this girl in despair.
