The series takes place in 2008 in Shibuya and focuses on Takumi Nishijou, a high school student at the private Suimei Academy, along with several strange incidents that have recently happened in the Shibuya area. Two incidents have occurred so far, and the media and the general public refer to them as New Generation events. The first incident, called "Group Dive," happened on September 7th, when five high school students jumped to their deaths from a tall tower. The second incident occurred on September 19th, when a man was found dead with a thirty-two-week-old fetus cut out of his abdomen. The story starts on September 28th with Takumi chatting with an online friend named Grim. Grim provides Takumi with background information on the recent New Generation events because Takumi is not interested in local or international news. A person named Shōgun joins the chatroom but does not say a word until Grim has left. Shōgun confronts Takumi and sends him a barrage of image links that depict a very gruesome murder. The next day, as Takumi is heading home after spending the afternoon at an Internet cafe, he comes across the same scene that he saw in Shōgun's pictures the day before. He runs away from the crime scene screaming, but not before meeting a pink-haired girl there who is covered in blood and wearing Suimei Academy's uniform. The story continues from here with Takumi trying to avoid getting involved with Shōgun and other New Generation events as he is slowly caught in the wheels of a grander scheme.
