Ep. 9

Summary

Source-backed · Version: v1 · Original

Faris overhears Okabe and Daru discussing the Phone Microwave and asks to use it, but a more immediate problem appears: the IBN 5100 has vanished. In the current world line, the lab never obtained it from Luka's shrine. Kurisu explains that earlier D-Mails may have produced a butterfly effect, changing events far removed from each message's intended target. Okabe confronts Moeka, but she claims not to know where the computer went. Unlike the world line immediately after her transmission, everyone now remembers her, showing that subsequent changes have overwritten parts of that reality as well. Faris reveals that she is Rumiho Akiha, daughter of the family that owns much of Akihabara, and offers information about the IBN in exchange for sending a message ten years into the past. Okabe reluctantly agrees without learning the message's content. After the shift, Faris's father says his family no longer possesses the computer. More visibly, Akihabara has lost its maid cafés, anime shops, and otaku culture, becoming an ordinary electronics district. A single private D-Mail has transformed an entire neighborhood, proving that the laboratory can no longer predict the scale of what it changes.
