Reiko Arisugawa (有栖川 麗子 Arisugawa Reiko?) is one of the main female characters in the Shomin Sample series. Reiko is one of the most popular girls in her school, and many want to be popular like her, including Aika. She also acts as the representative of the first year high school students.


Reiko is a tall, busty and very beautiful fair-skinned girl with straight butt-length blond hair that always has a white flower clip on the left side of her fringe to style her hair and turquoise-sapphire eyes.

Reiko is usually seen with a normal Seikain Jogakkou school uniform.


Reiko is considered the most innocent, pleasant, and cheerful girl in the school. She is someone who always acts positive, however, her personality drastically changes when she learns about Aika's plan to help her reconcile with her friends and classmates after an uncharacteristic outburst. She doesn't want to accept Aika's help and bitterly confronts her about her actions. In the end, the situation is resolved amiably, but in turn this breeds a rivalry for Kimito's affections.

Reiko is a highly respected and influential member of Kimito's class at Seikain Jogakkou. She welcomes Kimito after he first arrives at the academy. Like most of the other "Ojou-samas" at the academy she is ignorant to, and also captivated by, almost anything related to commoners.


Not so much known about Reiko's background, but she is from a rich family, and she lived with her mother, father and brother, although her father worked a lot to support Reiko's family. Also, in the Arisugawa family, every daughter enrolls at Seikain so they can be like their mother, grandmother and ancestors. Also, marriage is also important thing in the family. Reiko also is forced to get married, even though Reiko didn't want to get married. However, with the help of Kimito Kagurazaka, Aika Tenkuubashi, Karen Jinryou and Hakua Shiodome, (Mostly Kimito) her mother eventually accepts that she didn't want to get married and she tells Reiko to marry the one she wants.


Reiko is the first person that Kimito Kagurazaka meets upon coming to Seikain Jogakkou. Like the other girls, she was very interested in Kimito, and she later falls in love with him after a event. And after some time, Reiko joins the Commoner Club to stay close to Kimito and interfere with the advances of other girls. However, she comes to care for the girls in the club, and says that she wants to spend time with them in the club.


  • The name Reiko means "beautiful, lovely" (麗) (rei) and "child" (子) (ko).
  • Reiko's surname Arisugawa means "exist" (有) (ari), "nest, rookery, hive, cobweb, den" (栖) (su) and "river, stream" (川) (kawa/gawa).
    • Her married name Kagurazaka means "Shinto music" (神楽) (kagura) and "slope, hill" (坂) (saka/zaka).
