This was my Infected episode 7. Theory time, so you can all call me stupid later: All of the new LRIGs this time were born of the butterflies that came from Mayu’s body. Half of them were white, which are the good ones like Ril and Dona, and half were black, which are the bad ones like, well, you’ll see. This is why they seek human memories; because Mayu herself was never able to make them as she was never let outside. Looking forward to seeing how close that is to the truth.
