Ep. 8: Okabe explains world line shifts and Moeka sends a D-Mail altering reality.
Aired on May 25, 2011

Okabe clarifies to Daru and Kurisu that he alone retains memories of timeline alterations. He intends to continue experiments by having Kurisu send a D-Mail, but Moeka insists on sending it herself. This action shifts Okabe to a new world line where no one else remembers Moeka. The following day, Ruka arrives at the lab requesting a D-Mail to be born female, citing an urban myth about maternal diet influencing fetal gender. The group sends the message to Ruka's mother's pager, triggering another world line shift. Okabe notices no significant changes regarding Ruka and remains uncertain about the specific alterations in this new timeline.
