Senjuin Asuka

The he-iress in radiant curls.

Her pride in her own prestigious family is frequently a point of contention between her and Mikage.
She organizes and heads an extra-curricular organization called the "Friendship Sorority" a student group and political opposite to the Student Council led by Mikage.
She is known among students as "Empress of the Rose Garden".
Crossdressing is part of her family tradition, and she embraces it gleefully.
Has upmost confident in her own beauty and behavior and isn't afraid to show it.
Is quick to chastise her younger sister Mahiro, but is otherwise intensly adoring towards her.

Her family is so wealthy that she has a personal chef for lunch, built her own private dormitory, and generally seems to have no restraint in spending her family's money whatsoever.
If anything, her lavish spending seems to suggest she views spending money as her duty as a wealthy person.
Her opulent behaviour attracts many covetous admirers, but many enemies as well.
