About: It is not known who built Delta, as he is far more advanced than other cyborgs in the Haremverse, and has been around for as long as anyone can remember. Despite the mystery, he is known for being curious, cheerful and eager to help and please. He monitors all of the network traffic inside the Haremverse, and serves as a natural antivirus computer program that keeps everyone’s data safe.
He has a multicolored hair, rather than pure white hair. Delta's outfit is different though it's design is still somewhat based on it. Delta and 9S are both androids who's skill are related to scanning, as well as being nice and gentle individuals, well until his source loses it.
