17 years old. The Princess of the enemy nation Amidonia, but for the Amidonian citizens’ sake and the country, she intruded herself as Souma’s Third Queen Consort. She held an unique business sense, which she used to financially support Souma’s reign. She held no interest in politics and she intend to become a merchant only. She fit in the consort really quickly and always likes to make jokes yet is deadly accurate in pointing out Souma's thought process when concerning business and money.
Souma has always been impressed in Roroa's positive way of thinking. Especially when she invited herself to be one of his consorts and he was worried she'd hate him for killing her father but she told him they didn't get along and it was more important to have her citizens survive than to worry about a family member she didn't get along with in the first place.
