Ep. 4: Okabe and Kurisu seek the IBN 5100 to decrypt SERN's time travel data.
Aired on April 27, 2011
Okabe learns from Titor that the IBN 5100 is required to decode encrypted data regarding SERN's time travel experiments, which Daru cannot decipher. He encounters Kurisu while doing laundry and mentions the computer, though she remains skeptical about the existence of time machines. Her interest is piqued when a contact verifies the IBN 5100's capabilities. Subsequently, Faris Nyannyan reveals that an IBN 5100 was donated to Ruka's family shrine. Ruka's father confirms the donation, noting the donor predicted a young man would seek it out. This information allows Okabe and Kurisu to successfully acquire the necessary computer to proceed with their decoding efforts.
