The duke and the butler (KWMS)

Misaki was born to the noble family of the Ayuzawa Household. She was treated with the best of everything and she couldn't even think about worrying what to eat or what to wear.

All of that changed when her father had left her and her family suffering a large debt from the royal palace, due to the gambling tendencies of her father.

A few years later Misaki is now grown up, and determined to pay off her father's debt.

But how?

She sees a flyer on the ground, and there's a hiring for staff in the royal palace of Walker.

But there's only one problem.

She's a girl.
