With further information about SERN's time travel experiments encrypted in a code that Itaru can't decipher, Rintar? learns from John Titor that he needs the IBN 5100 computer Moeka was looking for to decode it. While doing his laundry, Rintar? runs into Kurisu, who is still in denial about a time machine existing. After Mayuri hears from her maid cafe co-worker, Rumiho "Feiris Nyan Nyan" Akiha, that she knows about the IBN 5100, Rintar? finds out that the computer is at the shrine where Ruka works. Rintar? and Kurisu borrow it from Ruka's father and carry it back to the lab.
