[Edit]
Instead of staying home and attending High School in Kyoto, Kyoko travels with her childhood friend Shō Fuwa to Tokyo to help him while he makes it big as an idol. When she finds out he only invited her so she could be his maid, her heart and innocence are shattered. More vengeful than depressed, she swears to avenge herself. Shō comments the only way to do this would be to beat him in show business, so that's what she decides to do. She changes her hair style and begins the task of applying to Shō's rival company (Akatoki Agency), L.M.E. While her audition stood out, the president of the company realized that she lacked the key point needed to become an idol: love, as without genuine love for this profession and for the audience, she cannot make it far in this world. However, despite her failure, she had such an interesting and impressionable audition (she did katsura-muki as her talent portion) that Kyoko is given a second chance. The L.M.E. "Love Me" section is thus founded. Lory makes a deal with Kyoko that if she whole-heartedly completes all the jobs given to her as a Love-Me employee to the client's satisfaction (which is determined by how many points they stamp onto her record book), by the end of certain period of time, when she has accumulated enough points, she will be given a grand debut. Thus begins her journey into the show business world.
As an actress, Kyoko is unrefined but creative and spontaneous, able to impress talent scouts with her unique talents and improvisations. In her earlier jobs, she utilizes the skills she learned from working in an inn in Kyoto Prefecture (like cooking, walking "properly," and performing a traditional tea ceremony) to act the part of a wealthy, cultured lady. Though passionate and hot-tempered, Kyoko is able to show impressive professionalism and discipline when it comes to acting, even to the point of putting the job before her health. When forced to perform a tea ceremony in a movie scene with Ren, she is able to keep a serene face and act her part while kneeling on a badly sprained ankle. Yet despite the pain, she refuses to get up or stop until she the scene is completed. Because of this, the director and everyone else was incredibly awed by her determination and strength. Later on, Shuhei (Kuu), Ren's father, says she was a "scary kind of actress," much like Ren. Her debut is for a soft drink commercial and her first major role was Mio, the antagonist in the television drama Dark Moon.
When she is in her room in "Darumaya" she is often seen explaining how she would exact revenge on the two men that make her life miserable to a large poster of Shōtaro and a small photo of Ren, the picture becomes much larger as the story progresses (the size of the picture reflects her level of hatred towards the person on it). She also carries with her many curse dolls of Ren and Sho, which she uses to vent her anger and perform curses. The dolls, incredible in the attention to detail, are handmade by Kyoko. They feature Sho and Ren in various state of fear, distress and submission. After her relationship with Ren improves, she often 'consults' her Ren doll during times of stress.
She becomes a regular in a show wearing a chicken suit for the character "Bo". She assumes this character on several occasions to talk to Ren, because he won't open up about his problems to anyone he knows. She likes to cling to Kanae and calls her "Moko" (it is seen in volume four that every girl hated Kyoko for her familiarity with Shou). Kyoko never liked to drink soda (even as a child) but she made herself drink it for an important commercial audition. Kyoko seems to have a bad relationship with her parents. Her mother, Saena, was a strict and emotionally distant parent who eventually left her with the Fuwa family when Kyoko was still six. The effects of Kyoko's difficult childhood can be seen throughout the series, particularly in her acting. For example, when Kyoko was acting with Maria, she stated that parents that despise their children really do exist. Kyoko's father has been absent throughout the series.
Kyoko has a noticeable crush on Ren, but she mistakes it for respect sometimes and even denies it since she "couldn't possibly let herself fall in love again". After seeing the certain scene where "Katsuki" (played by Ren) is looking at the girl he loves in the play, Kyoko remembers the smile (he has shown it for her a couple of times before) and comes to the conclusion that Ren might not hate her or dislike her, as she thought before. It is shown that Kyoko does not know that Ren is "Corn" her "fairy-prince". Recently, she was the caretaker for Kuu (aka Shuhei), an actor who played in the previous version of the drama "Dark Moon". He is also Ren's father, although Kyoko does not know this.
Kyoko has a fondness for cosmetics, fairy tales and anything magical. However being betrayed by Shō has left her cynical, especially about love. It seems that Kyoko's birthday is on December 25 as Ren gave Kyoko a rose saying "Happy Birthday" as the clock struck 12:00 midnight at Maria's birthday party (whose birthday is the 24th), and the rose is also very special, as the rose is very large and contains a gemstone (purposely put by Ren which Kyoko later uses as part of her necklace in Act 128).
After Dark Moon started airing, Kyoko was cast in a high school drama as Natsu, which is a "Bully Role"; however Kyoko runs into the problem of being type-cast, as the director asks her to do her "Natsu" role based on "Mio". This is in spite of the fact that two roles should be different, as Mio is an extremely embittered rich young heiress, while Natsu is a relatively normal girl from a normal family who merely likes to pick on her classmates. But after some training from Ren on "how to act like a model" she stuns the cast with her new appearance and attitude for the role of Natsu, easily impressing the director with this new representation of Natsu.
However, later on a cast member, jealous that Kyoko was able to bounce to another roll so easily where she never could, pushed her down a flight of stairs. Though she fractured her hand and knows who did it Kyoko doesn't tell, but instead has that cast member be her "right hand" with her bullying.
