In this world line, Rintarou sends another D-mail to Faris's father, hoping it will keep him from dying along with Mayuri. After the D-mail is sent, his timeline is severely altered. The laboratory never existed and he never met Mayuri, Daru or Kurisu. In this new past he was a participant in the Rai-Net Access Battler game, where he met, partnered with, and became lovers with Faris. Realizing that without the laboratory, he has no way to create a new timeline, Rintarou decides to accept this new past and start a new life with Faris by his side.
