Arisugawa, Reiko

Reiko is a highly respected and influential member of Kimito's class at Seikain Jogakkou. She acts as the representative of the first year high school students, and 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."

[Spoiler] Not long after arriving at the academy Kimito walks in on Reiko in the baths and they see each other naked. After this incident, Reiko develops a crush on Kimito and often has delusions of marrying him. [/Spoiler]
