Girls Kingdom: Volume 1

All Misaki wanted was a free education. Instead, she accidentally lands an exclusive contract with the most prestigious girl in school. . . to serve as her personal maid! Misaki soon discovers that Amanotsuka Academy for Girls is no ordinary school-her classes are all about how to be a maid, too! Students who impress the school's elite young ladies with their domestic service skills might be lucky enough to become a "Seraph," guaranteeing them a job with an upper-class household after they graduate.
But Misaki doesn't want to be a maid; she just wants to study hard, go to college, and work for a good company. So why did Himeko make her into her Seraph out of nowhere? What kind of rich girl hires a maid who wants nothing to do with the job? ! If she wants to get through high school, Misaki has a lot to get used to!
