Then, in the shower, I thought that there was a group of these "Enigmas" like Figure and Cruncher that had broken out of a secret facility. So, they destroyed the facility, and broke out. The goal of the arc would be to recollect all of the other "EEs" (escaped enigmas) and either kill then or free their hearts. Along the way, we learn about the EEs past lives and how it was being "SEs' (secure enigmas) and how they were turned from normal people or animals into these enigmas.
