Unable to shoot the alien, Kei lowers his gun, enabling Nishi to secure the points and end the encounter. Nishi informs the survivors that anyone still alive may return home to recover. Kei and a girl attempt to rouse the near-deceased Katou, but he merely survives. Back in the room, scores are revealed: Nishi receives three points for a total of 90, while others receive none. Nishi explains he has visited the room for a long time, where it creates fax copies of people just before they die. The group demands to know why he withheld this information, and he casually states he wanted the target to drop his guard. His cold rationality enrages them, but Nishi demonstrates his superiority by clenching Katou's wrist. When Kei threatens him with a gun, Nishi becomes invisible and departs. Kei later wakes in his apartment, seeing news reports of the earlier deaths, including his own. He realizes the experience was not a dream upon noticing a suit lying on a chair in his room.
