Little Busters! EX EP4 - EX 4 Someday, Somewhere...

It is revealed that Saya's father works as a doctor and while at work overseas, she was taken with him and she was given a manga which she treasured dearly. When she returned to her hometown, she meets Riki and they play ball together until it starts to rain. On the way home, a mudslide seemingly kills Saya, but not before she enters the artificial world Kyousuke created. She is repeating the same scenario, and dies every time, thus making Kyousuke rewind time. In one of the replays, Saya and Riki face Tokikaze Shun, the antagonist of the manga Saya loved so much, which, coincidentally, Saya is the protagonist of the same manga.
