Kill la Kill - Episode 16
All the backstory about life fibers is finally revealed, and Ryuko's and Senketsu's roles in the ultimate confrontation with Ragyo Kiryuin. But what if Ryuko refuses that role, and Satsuki too?
So much exposition, from the Kiryuin side and the Nudist Beach side. Here's what we now know: the life fibers are alien parasites who feed off the nervous system of animals. They chose humans to be their best hosts for their developed cerebra, and subtly improved their evolution so that one day, the life fibers could feed off them in a grand harvest. It was Ragyo Kiryuin who somehow came into possession of the big ball of life fiber, and hatched her plan to make Revocs clothing (a backwards writing of Cover, which is what the life fibers want to do) ubiquitous, and awaken the life fibers sewn into each one when humanity was ready. Dr. Matoi, Ryuko's father, found out about the extraterrestrial nature of the life fibers while researching them for Revocs, and formed Nudist Beach to oppose this harvest. He created an artificial life fiber suit to be worn by his daughter, who was extremely tolerant of the draining effect that life fibers have on their hosts. But before he could present the suit to Ryuko or Nudist Beach, he was attacked by Harime the Tailor, which brings us to the beginning of the show.
