Steins;Gate - episode 1 - 05 Apr, 2011

In the summer of 2010, self-proclaimed mad scientist Rintar? Okabe goes to Doctor Nakabachi's seminar on time travel with his friend, Mayuri Shiina. While there, he meets a girl named Kurisu Makise who explicitly states that he had met her 15 minutes ago, despite having never seen her before. After bluffing his way away from Kurisu, Okabe then receives a mysterious video message on his phone that is scrambled when he opens it. Later on, Okabe hears a scream and sees Kurisu lying in a pool of blood with signs that she was stabbed to death. As he sends a text about it to one of his fellow "lab members," Itaru "Daru" Hashida, Okabe feels a strange sensation, suddenly finding the street he is on to be deserted and discovering a strange satellite has crashed into the building he was just in. Later on, while fiddling with their strange remote-controlled microwave oven, which turns bananas into a gel-like substance, Daru tells Okabe that the seminar he supposedly attended was cancelled, much to his surprise. Okabe later discovers that the text he sent to Daru was received a week before he sent it, just before encountering a very much living Kurisu. (Source: Wikipedia)
