壬無月 葵

Aoi is a pretty girl attending a girls-only private school.
As intelligent as she is beautiful, she still ranks second to her idiot brother
who is sure to doom the family if he inherits everything.
What's a daughter to do? Aoi decides to crossdress, attend her
brother's school, and graduate pretending to be a boy.
It will be a grueling three years of secrecy...
