So tell me how stupid this theory truly is, what I believe will happen is as the series progresses each spirit will be forced to reverse (go inverse, don't know the proper term) what if the final inversion which will surely be forced by DEM somehow will be Kurumi (I know up to this point has been theorized hundreds of times but hear me out) then the new inversed Kurumi will then begin to use her 8th bullet on each spirit to summon a clone of their past under her control or more particularly their inverse form under her control, and while inverse the 8th bullet is capable of summoning the clones at near full power, sorry about the stupid post just had to write this down somewhere
