Nanako is a sweet and generous 16-year-old girl, who just wants to "be loved by the others, even if only a bit", and doesn't mean to harm anyone. She is suddenly plunged into a world that may change her deeply, as she becomes a member of the Sorority, a prestigious school organisation that only the richest, most beautiful and sophisticated girls can access, the dream of all the youngest students.

Nanako's admittance, decided by Lady Miya, will set in motion around the young character a real storm of envy, "retaliations", and threats, causing Nanako's disbelieved desperation before so much violence addressed towards her. After losing for some time Tomoko's support, object of sometimes excessive attentions from the devoted and troubled Mariko Shinobu, Nanako finds comfort in the letters she writes to her "dear brother", Takehiko, in the friendship of Kaoru, who protects her more than once, and most of all in her deep interest for the charming and mysterious Saint Just, who Nanako probably feels very close in her sufferings...

In the end, Nanako will be deeply affected by her experiences at Seiran, by the contact with a world that taught her what jealousy, envy and torments behind her imagination and innocence are....

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..

She works for Group Komadori. Her debut animation was "Ginga Hyouryu BYFAM".

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.
