Sae knew something had happened to Makoto. One day, she decided to secretly follow her sister to her supposed work at the laboratory. However, she was soon ambushed by Makoto herself and was thrown into the testing chamber naked. Sae protested at Makoto just as her sister flicked the power switch. Sae tried to resist as long as she could, but when the corruption had reached her mind, she could no longer hold on and Shadow Sae soon emerged in her place.
