2030 A.D.

In the face of growing intensification of heinous crimes committed annually, an enormous number of victims follow one after the other, even on account of the police, who must be keeping public order in towns. Accordingly, it was devised that man and beast would be genetically combined to oppose people that commit heinous crimes: this new race with multiple strength increases were called "Newmans." From there, that technology was further utilized, and artificial life forms called "Newmanoids" were produced.
