Talk:Reiko Mikami/@comment-54.219.163.110-20150116055832/@comment-6052796-20150116085541

There were hints sprinkled throughout the show that lead to the killer. One of which was when Kouichi finally got a grasp about what was happening to Mei and him. Chibiki spoke to him of another Non-Existent student that broke under the pressure and demanded that he existed. I assume Izumi's cousin was that Non-Existent student and snapped when people refused to acknowledge him. Even the kinder gentler Mikami couldn't break character to talk him out of his kill because it would break the charade. She died trying to keep the rest of class 3-3 from dying so to speak and she died again for that same reason only through different circumstances. As for her parents, it's perfectly clear the grandfather knows she's dead, but the grandmother keeps shutting him up when he mentions anything hinting to that, such as "poor Reiko"  It was said that people with mental disorders, seniors and animals aren't effected by the Calamity's memory problems like the young are. The grandmother could see her and the younger adults could see her, including Matsunaga, who vaguely hinted he may have visited her funeral. Another way of looking at it, would be that Reiko's death devastated the grandmother the most and she's spending it in denial, pretending that Reiko exists and her being the extra and living flesh and blood as that extra doesn't help matters any further.
