===The Sorority===
:The Seiran Sorority is an amalgamation of a student government, an extracurricular club, and an elite society, and is a school tradition that is said to date back to at least the 1930s. Similar to western [[fraternities and sororities]], prospective members seem to be nominated by those already in the Sorority, and undergo a pledge period in which they are interviewed for fitness. Family legacy, appropriate extracurricular activities, and attractive appearances are the main considerations for admission. The Sorority appears to have around forty or fifty members, though several of the senior members are given prominence and special nicknames. They are primarily referred to by these nicknames, though later in the series their surnames are revealed. Their given names were never shown.

;"Lady Borgia" Ogiwara
:{{Voiced by|[[Emi Shinohara]]}}
:Borgia is a senior member of the Sorority, and is commonly seen wearing her hair in a [[chignon (hairstyle)|chignon]]. Her position in the Sorority is never expressly stated. During the Petition Arc, she is presented as the most adamant member of the plot to discredit Fukiko, with intentions of taking over as President, herself. She holds a strong dislike of Fukiko and shows frustration with the other girl's staunch pride.
;"Lady Mona Lisa" Komabayashi
:{{Voiced by|[[Shinobu Adachi]]}}
:Mona Lisa is a senior member of the Sorority, and resembles her namesake, possessing long black hair and an enigmatic expression. She is stated as being the Sorority's Vice-President and a good friend of Ogiwara. Reserved and mysterious, she is quite invested in the Sorority. She eventually goes along with the other members during the Petition Arc, though contests Borgia when she realizes their machinations have gone too far.
;"Lady Medusa" Katsuragi
:{{Voiced by|[[Kumiko Takizawa]]}}
:Medusa is a senior member of the Sorority, and briefly serves as Vice-President after Mona Lisa's resignation. She has bushy brown hair. She appears to be Fukiko's only friend within the Sorority; the two are often seen conversing pleasantly, and during the Petition Arc she is the last member to remain on Fukiko's side.
;"Lady Cattleya" Yamamoto
:{{Voiced by|[[Satoko Yasunaga]]}}
:Cattleya is a senior member of the Sorority, and has curly brown hair with side-swept bangs. Cattleya plays a role in the conspiracy to discredit Fukiko, though she pulls out when Borgia's schemes prove too ridiculous. She seems fairly kind, and willingly helps Nanako with the petition after resigning.
;"Lady Vampanella" Hoshino

:Vampanella is a senior Sorority member, and wears her dark hair in a ponytail with a bow. She appears close with Cattleya; the two both abandon Borgia to her schemes during the Petition Arc. She is seen to be a [[Smoking in Japan|smoker]] outside of school.
