Rumiho learns about the Mobile Microwave as Rintar? discusses it with Itaru, becoming very interested in it. Later, Rintar? discovers that the IBN 5100 has gone missing, as if they never found it in the first place, most likely as a result of Moeka's D-Mail. After learning that the IBN 5100 had been previously taken from Ruka's shrine, Rintar? finds Moeka in town, but she doesn't know where the IBN 5100 is either. Rintar?, Itaru and Mayuri go to see Rumiho, whose family owns Akihabara and originally donated the IBN 5100 to the shrine. She offers them a replacement in exchange for being allowed to send a D-Mail ten years into the past. As history is altered again, the IBN 5100 was never donated to the shrine and, more disturbingly, the face of Akihabara has completely changed, no longer being a mecca for anime.
