Biography[]

When she was in junior high, she confessed her love to a male friend of hers named Ginta, but it was a disaster and Miki ended up heartbroken. Eventually she got over it and became friends with him again.

While Miki was in high school, her parents went on a trip to Hawaii and decided to swap spouses with another couple. The other couple had a son the same age as Miki, and they all moved into a large house to live together. That boy was Yuu Matsuura. At first, he is always teasing Miki, and she thinks he is annoying and rude. One day a ball hits her head and Miki faints. While she is in the nursery, Yuu comes to pay her a visit, and Miki pretends to be asleep. Yuu thinks she is asleep and kisses her, which was both their first kisses. They started spending more time together, and Miki ended up liking him. However, Miki was a really insecure girl and became jealous because Yuu was always surrounded by other girls, several of them being very beautiful while Miki believes herself to be only average-looking. Thanks to Yuu, Ginta starts having feelings for Miki and tries to win her heart again, which makes her confused about her true feelings for them.

Initially she has medium-length hair and puts it in a ponytail or twintails, but shortly before the wedding Meiko cuts it short and pierces her ears with gold stud earrings. She keeps this haircut even as an adult. She is often described as plain-looking, but she is pretty enough to be liked by at least four guys. She has been seen in many different clothes but usually prefers tank tops, shorts, socks and sports shoes. But when she puts on a festive dress, shoes and makeup, she becomes fabulously beautiful.

Relationships[]

Yuu Matsuura[]

Yuu and Miki started to fall in love with each other as they came to know each other better. However, Miki was very uncertain of herself and became jealous because Yuu was always surrounded by other girls, several of them being very beautiful and mature while Miki believes herself to be only average-looking and childish. She and Yuu eventually become a couple but doesn't tell their parents because they know their parents would annoy and tease them. They confessed their love to each other in episode 25, and started dating in episode 26. Due to Yuu being away in New York, and Miki tired of worrying all the time, she broke up with him in episode 62. But the two got back together in episode 71 when he returned for summer break. A misunderstanding causes Yuu to believe that they are half-siblings, and he breaks up with her without telling her the real reason, thinking the truth would be more painful. But after some time trying to make the right decision, they decide to marry and ask for their parents' approval. There, they learn that they are not related and receive their parents' blessing. By the end of the anime, they marry; at the end of the manga, they make plans to marry after college. In Marmalade Boy Little, after living together for 13 years, they get married and have two children named Fū and Kokona.

Ginta Suou[]

Ginta Suou (須王 銀太 Suō Ginta) is Miki's best male friend and a member of the Toryo tennis team. Miki has had a crush on him since junior high and confessed her feelings to Ginta in a note. However, the note was found by Ginta's classmates, and Ginta downplayed it, without knowing at the time that she was watching, although he felt the same way about Miki.

Although he did find out that Miki had witnessed his denial of any interest in her, he was unable to tell her how he really felt until high school. The romantic tension between them comes to a head with Yuu's appearance, which makes them realize that they still have feelings for each other. He decides to go along with Yuu's ex-girlfriend Arimi's proposal that they pose as a couple in order to drive a wedge between Miki and Yuu. In the process however, he starts to develop genuine feelings for Arimi, which she later reciprocates.

Meiko Akizuki[]

Meiko Akizuki (秋月 茗子 Akizuki Meiko) is Miki's best female friend. Meiko is the only child of wealthy parents and is very mature and beautiful. Meiko is always there for Miki and can always tell when the boys are being jealous. She is the first one to notice. Meiko is Miki's best friend since the seventh grade. Meiko is the more mature one out of the two and she is always there whenever Miki needs her. She is always giving Miki some advice when it comes to love life and family.

Kei Tsuchiya[]

Kei Tsuchiya (土屋 蛍 Tsuchiya Kei) is Miki's coworker at Bobson's ice cream parlor who is a talented but troubled pianist. He also falls in love with Miki, and tries to use Miki's lost medallion to cause Yuu to think Miki doesn't want him anymore. This fails however, as Yuu sees through his lies and, though he fights with Miki, they make up. Miki yells at Kei for his immaturity, and forgives him. After some convincing by Miki to regain his confidence in music, Kei quits his job at Bobson's ice cream parlor and says goodbye to Miki, promising to return soon. After Yuu and Miki broke up, they started dating but stopped when Yuu came home.

Arimi Suzuki

Arimi Suzuki (鈴木 亜梨実 Suzuki Arimi) was not on the best of terms with her from the start. Miki was worried that Yu might go back to her because she is much more feminine and beautiful. Arimi, for his part, hates Miki and thinks that she is unworthy of Yu because she can't choose between Yu and Ginta. But once Arimi starts dating Ginta, their relationship improves and they start spending time together as friends. Miki helps her and Ginta to reconcile during their arguments, and in turn, Arimi supports her during Yu's trip to America.

Tsutomu Rokutanda

Tsutomu Rokutanda (六反田 務 Rokutanda Tsutomu) initially annoyed her like everyone else and she also found her heated behaviour ridiculous and mocked him along with Ginta and Yu. He in turn had little interaction with her. Nevertheless, she enlisted his and Yayoi's help to reconcile Ginta and Arimi. She is also happy for him that she has a new love now.

Yayoi Takase

Yayoi Takase (高瀬 弥生 Takase Yayoi) has known her for not so long, but they are very close. She met her before Kei's concert when Rokutanda introduced her to everyone else as his girlfriend. When the girls were teaching Miki how to use the gadget to communicate with Yu, Yayoi told her that her boyfriend gave her the exact same one, and Miki was immediately interested in her friendship as she found her mellow personality and her rich imagination very cool. Since Miki found Yayoi interesting and versatile, she likes her much more than Rokutanda and since she met her through him she can't exclude him from her social circle. Thanks to the way she and Rokutanda helped her reconcile Ginta and Arimi, they became very close. Like for everyone else, Yayoi supports Miki and helps her. They are very trusting and loyal to each other. Yayoi enjoys having the fearless Miki as a friend and gives her cooking lessons, dispensing with criticism unlike Yuu. Miki enjoys her songs and food, especially her desserts. She is also fascinated by the number of animals Yayoi keeps at home, and even has a puppy from her. However, she thinks that Yayoi is too good for Rokutanda, but does not try to destroy their relationship probably because she believes that their love for each other is genuine and that Yayoi has revealed Tsutomu's latent goodness.
