Something I have been wondering for a while now, does the exposure to the light also affect kyou even though the beam isn't directed at him? Does he inadvertently manipulate his own perception of reality when he hypnotize others? I mean, even if it isn't used on him the patterns are still in the light, and we saw that they were strong enough to put someone in a trance despite being many buildings away. It would also explain why Kyou seems to actually believe that, in the robot ending, Nozomi and her friends are actually robot despite being fully aware at first that it is all a ruse.
By the way, I love the way you write this story. It is obvious that you actually interested yourself on the subject of hypnosis. It feels so refreshing to have a media which doesn't shows hypnosis as a all powerful tool made for evil purposes (even though it is what ends up happening). I wish there were more content like yours.
