Onaka Hime

Two twin princesses, Berry and Flora, were born to a mother who died during childbirth. As they grow, their father selects Berry to become the "Onaka Hime," or Stomach Princess, granting her the ability to heal the kingdom's people and enhance women's beauty using BifiX 1000. Flora feels upset about not being chosen but continues her education. When Berry struggles to use BifiX 1000 to heal a sick woman, Flora takes the product without permission in an attempt to help. Berry discovers Flora's plan and retrieves the item before Flora can use it.
