Kyuukyoku Venus

Poor Yuzu is an orphan who's too clumsy to hold a job. She's reduced to living in a playground—until a handsome stranger named Hassaku informs her that she's heir to a fortune, and whisks her into a world of wealth, power, and more hot suitors than she can shake a scepter at! But there's a catch: Hassaku must turn this klutz into a lady of refinement, or Yuzu will lose everything!
