In return for a business loan of 50 million yen, the prestigious Kamiya family gave their daughter Haine away to the Otomiya family. Haine, now an Otomiya, is appointed to the student council of the exclusive Imperial Academy, a private school for the aristocracy. Even though Haine is of proper lineage to be on the council, she finds herself struggling to find her place among the many secrets of its elite members, especially those of the president who holds her heart--Shizumasa Togu, aka "the Emperor."
Learning the truth behind her parentage and the reason she was put up for adoption, Haine reverts to her yanki ways. She rejoins her gang and comes up with a plan to break into the Kamiya mansion to abduct her mother. The only thing standing in her way--the twins!
