Being the waitress and owner of a moe cafe, Faris would always adds "Nya" to her speech as to boost her "moe-ness". She has an ability to see into people's hearts just by looking into their eyes, which she calls the "Cheshire Break". She has a father complex, while at the same time apparently harboring feelings for Rintarou (see episode 17).
A long time friend of Rintarou, she likes to play along with his delusions and comes up with scenarios herself. Faris is one of the few people who does not think of Rintarou as "weird".
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.
