Yuma is an athletic girl and is out-going. She pretends to be always in conflict with Takaki and that he's always trying to beat her in everything. She thinks he is her rival.

Her best friend is Manaka Komaki.
Prim and elegant, Sachiko has a rough side and a very sweet side. She is very protective over Yumi and cares deeply about her. However, Sachiko often has the same problem as Yumi does — she does not share most of her problems with her sœur, causing many misunderstandings. Sachiko is slated to marry her cousin and fiancé Suguru after she graduates. This has caused her some distress since, because although she initially cared deeply for him, he did not reciprocate. They now have a complicated relationship. Sometimes, Yumi must teach Sachiko how to live informally, for example, helping her select her first pair of jeans. Despite her sometimes stern appearance, Sachiko has her own share of insecurities regarding her relationship with Yumi, not to mention emotional insecurities rising from her home life; both her father and grandfather openly have mistresses, unabashedly dividing their time between home and the mistresses, which apparently led to her general disdain for men, as illustrated in the OVA series during a meeting with the student council members of Hanadera, an all-boys highschool. After Sachiko enters her third year, she is now the new Rosa Chinensis. After the arrival of Touko, Sachiko spends more time with her than with Yumi, which makes Yumi jealous. Sachiko goes absent from school which makes Yumi worried. Later, Youko is sent to "bring" Yumi to Sachiko's grandmother house. Yumi finds out that Sachiko's grandmother recently died, which causes Sachiko to go into depression. Sachiko says that she apologizes for the past few weeks, and asks for Yumi's forgiveness; Yumi says that she loves her very much. At the beginning of the summer holidays, Sachiko takes Yumi to her summer home. Whilst there, Sachiko's acquaintances make trouble for them. Yumi intends to leave, but Sachiko refuses. The acquaintances have a party, and invite them. At the party, they ask Yumi to play a musical instrument for Sachiko's great grandmother. Yumi says that she cannot play anything and prefers to sing the song "Maria-sama no Kokoro"; Sachiko accompanies her with a piano performance. The great grandmother is happy because the song brings back memories, and she asks Yumi to visit next year. In the first season, Sachiko is Rosa Chinensis en bouton, her grand soeur was Mizuno Youko, and her petite soeur is Fukuzawa Yumi. In the second season, Sachiko becomes Rosa Chinensis.
The exact opposite of most of the characters in the show: loud, rough-around-the-edges, she loves doing what she can to push other peoples' buttons. She enjoys mercilessly teasing or being mischievous, conducting most of her antics around Fukuzawa Yumi. Despite being a non-conformist in the ranks of the regular girls in Lillian Jogakuen, Sei is one of the wisest and caring characters on the show. Though seeming to have a playful and laid-back attitude, she has experienced many tragedies in her life, especially in her second year. Sei is known for doing things at her own pace, and dislikes being pressured into making decisions and taking action. She took Toudou Shimako as her soeur while in her third year. Her relationship with the first year is seen to one of mutual understanding and selective support. Sei however has an especially close relationship with Yumi. Sei becomes a source of comfort, and emotional outlet and close friend and mentor for Yumi. She is often noticed by others for her unconventional looks; many strangers have assumed that she is a model. Sei is not purely Japanese, and has Anglo features, as seen by her hair and eye colour as well as her Caucasian facial bone structure. After leaving Lillian, Sei studies English and American Literature. Part of this could result from her bibliophile behaviours she picked up during her second year in Lillian when she immersed herself in reading as a form of escapism and trying to understand her conflicting emotions during that time. She drives a yellow Beetle and is a terrible driver.
Being a shy, timid girl, Haruka is set up with Takayuki by her friend, Mitsuki, while she is in high school. The two quickly become close, and develop an intimate relationship. She takes in an interest in collecting picture books. Very early on in the series, she is involved in a serious car accident and ends up in a coma. The main thrust of the story begins when she awakens three years later. She is afflicted with anterograde amnesia, and because of her delicate psyche, her family and Takayuki conceal the truth that three years have passed, which forms much of the tension in the series.

Lucy is an alien girl who doesn't have much expression and doesn't have any friends. In the anime, she introduces herself to Takaki's class as 'Ruuko Kirei na Sora', which means 'beautiful sky.' She meets Takaki in the sixth episode of the anime, but we see her in an earlier episode without any dialog. She refers to herself as 'Ru', the name of her home planet and the beings on it, and to earth and earthlings as 'Uu'. She greets people by reaching for the sky and saying, 'Ru!' Himeyuri Sango in particular enjoys mimicking Lucy's greeting. Lucy has a cat that almost drowns in the sixth episode but it is saved with the help of Takaaki; Lucy summons a thunderbolt which splits a tree, forming a bridge which Takaaki crosses to lift the cat out of a raging river. Lucy terms this stray cat 'the Nya', saying that it is a special species that can enjoy the true taste of food, and like Ru, Nya is alone on Uu. Lucy likes to cook the Nya fish broiled over a charcoal clay pot, which according to her is the best cooking device available on Uu. Apparently a currency of Ru is matchsticks, one of which is enough to buy a whole rocket engine. Lucy irritates the cafeteria cook of Takaaki's school by attempting to treat Takaaki to the best meal the cook can prepare by paying the cook first one, then two matchsticks, however Lucy is somehow able to successfully purchase her charcoal clay pot and fish to br with matchsticks. Lucy says that on Ru, it is said that the only good Uu is a dead Uu, but Takaaki is a special Uu.
