@NihilistNeet I think what was implied by Jack is that the seven lucky gods are actually part of a greater whole, thus zero their true combined form. Essentially they are one being, inhabiting seven bodies thus the aura we saw uniformly covers all of them and is the same texture for lack of a better term, there is no distinction between the seven.
@ChampofFate Ohh so it is like that! I wasn't sure if the artist was going for that or if it was trying to depict everyone being differentiated by the number of "rays" sticking or something like that
