Human bodies consisted of the elements of wind, water, earth, fire, metal, and wood, and advanced tactics were able to infuse these basic elements into the attacks, like Einherjar Wannabe’s thunder attribute that actually belonged to the element of wind. In order to achieve so, one must first identify his or her own element. Elements were represented by a few genome nuclear sources, and these genome nuclear sources first had to be identified during the developing process of GN Force.
