Ep. 13: Okabe attempts multiple time leaps to prevent Mayuri's recurring deaths in the lab.
Following Mayuri's death, Suzuha creates a distraction in the lab, enabling Kurisu to use the time leap machine to send Okabe back to 5 p.m. that same day. Okabe evacuates the lab and searches for Mayuri, during which Kurisu calls him and deduces the time leap. Upon finding her, Okabe tries to flee to the station, but trains have stopped. When Rounders approach, they attempt to escape, but Mayuri is killed again by Moeka's car. After escaping the Rounders and leaping again, Okabe finds Mayuri earlier and heads to the subway. However, she is killed once more when Yuugo's daughter, Nae, accidentally pushes her into the path of an oncoming train. Devastated by these repeated failures, Okabe vows to continue leaping into the past until he successfully saves Mayuri.
