A very beautiful girl, unquestioned leader of the Sorority and President of the Student Council. Elegant and refined, Fukiko influences and controls everyone around her, determining their happiness or despair. She has a capricious character, both able of extreme tenderness and chilling wickedness.

She seems to have a liking for Nanako (and we'll gradually understand why) and she'll help her become a member of the Sorority, causing a real storm around the young character. Her attitude towards Nanako, however, will always be stressed by several ups and downs, mainly because of Nanako's relationship with Takehiko (and partly with Rei). The main target of her gratuitous wicked actions, however, is always Rei, with whom she has a mysterious and complicated relationship... 

In her "anime" version we get to discover something more of Fukiko's past and secrets, and in general she's better described than the manga, revealing a "nobility" (especially in the end of the story) and dignity somehow lacking in her manga version.

Before leaving her cram school, Nanako Misonō asks one of the teachers if they can become pen-pals. The teacher, Takehiko Henmi, is reluctant at first, but eventually accepts the offer. The story is narrated through the letters sent from Nanako as she enters Seiran, a renowned private high school for girls only. There she encounters many difficulties as an ordinary middle-class girl invited to the prestigious Sorority, the most traditional and sophisticated club on campus..

A classic manga about girls at a private all-girls school. The storyline centers around the experiences of Nanako, a "normal" girl who is invited to join the prestigious school organization, the Sorority, and is resented by all the other students because she doesn't appear to be qualified. Other key characters are Nanako's two friends: Tomoko, her friend since childhood who is alienated by Nanako's decision to try to join the Sorority, and Mariko, a strange, obsessive girl who is invited to join the Sorority along with Nanako; her "older brother," Henmi, who she corresponds with by mail; and the "Three Magnificent Ones," all of whom are admired and quasi-worshipped by the rest of the student body: the head of the Sorority, Miya-sama, the haunted, pill-popping rebel, Saint Juste, and the star athlete with a mysterious disease who doesn't like the Sorority, Kaoru-no-kimi.
