Faris NyanNyan (フェイリス・ニャンニャン, Feirisu Nyannyan), real name Rumiho Akiha (秋葉 留美穂, Akiha Rumiho), also spelled Feyris in the anime, is a part-time employee and owner of the maid cafe May Queen Nyan-nyan, the same maid cafe that Mayuri works at, and is the most popular waitress there. She is a second year student in Kanaria Private Academy and is Yukitaka Akiha's daughter.
Faris is a short girl with long pink hair and pink eyes. She prefers having her hair tied rather than having it down.
She is usually seen wearing her work uniform, a maid outfit with a head dress, apron with a ribbon at the back and black leggings with black shoes. She also has a redish ribbon around her neck and on the sides of the head dress. She has a wristband that is black with white frills to go along with the frills on the skirt.
Her casual outfit consist of an amber dress and a black tiara. As usual, she ties her hair into two braids and she doesn't wear the cat ears.
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 likes to play along with Rintarou's delusions and comes up with scenarios herself. Faris is one of the few people who does not think of Rintarou as "weird".
Her real personality is of a childish and charismatic girl who really misses her father. She does not often show this side to others and instead hides behind other masks like 'Faris NyanNyan'; this is one of the reasons she gets along so well with Rintarou.
Faris comes from a wealthy family that owns much of Akihabara - she even has her own butler, Kuroki. As such, she tells very few people about her heritage, out of fear that they will treat her differently. The lab members are among her only friends that she trusts enough to show her true self, 'Rumiho' to. Aside from her close friends, the only person she confides in is Kuroki, her butler. She is not able to have a very close relationship with her mother because she is often overseas and only comes back for short periods of time. As a result of having very few people to confide in since she was young, Faris has become quite a lonesome person.
Faris appears to be ditzy and foolish to go along with the persona she created, 'Faris Nyannyan', but she is actually quite perceptive and intelligent. However, Faris is also childish and cutesy at heart, as well, but she often exaggerates when she's 'Faris Nyannyan'.
As a child, Rumiho dreamed of one day opening her own maid cafe. She begged her father constantly, to no avail, though exactly why he wouldn't let her is never made clear. Ten years before the beginning of the story, to celebrate her eighth birthday, she had her father make a promise to drop work and join the party, but he ultimately cancelled because of a business trip. This made Rumiho really upset and she took it out on him, that he accused him of loving his job more than he loved her and told him she wished he was dead. Grief-stricken, her father decided to take an early flight back, and, in a painful case of irony, died in a plane crash. With her father gone, Faris was free to establish her maid cafe, but she always felt deep grief over his death, especially since the last thing they did was fight.
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.
"In order to protect your important friends they wouldn't tell the truth...or tell white lies. Being able to make friends like that...that is a very happy thing." - Speaking to Nae in Linear Bounded Phenogram.
"That scar will one day become a scab and flowers will bloom. Even within Nae's heart, they'll probably grow. Until then you should face the wound while thinking of the loneliness of being left behind. At the same time you should be thankful for each day." - Speaking to Nae in Linear Bounded Phenogram.
- The electronic district of Tokyo was owned by her family, hence the name "Akihabara".
- Lab Member 007. She joined in episode 9, recruited by Rintarou because she wanted to make a D-Mail to avoid her father's death.
- In the side story following Faris in Linear Bounded Phenogram, it's noteworthy that while she refers to Rintarou as 'Kyouma' without an honorific, in her mind she thinks of him as 'Okabe-san'.
