Steins;Gate is set in the summer of 2010, approximately one year after the events that took place in Chaos;Head, in Akihabara. Rintarō Okabe attends a conference on time machines when he discovers the bloody remains of Kurisu Makise, a renowned researcher whom he met earlier. Following this incident, Rintarō experiences various unusual events, leading up to his urge to test a machine he created to — apparently — travel back in time.
