Millhiore Firianno Biscotti

The 14-year-old Princess of Biscotti Republic, she has a gentle and hardworking personality. As the representative leader of the nation, she is loved by everyone in the nation. She is also a singer at the same time, holding events and concerts and appearing in person in front of everyone despite her status. She is also the one who summoned Cinque to Flonyard in the first place, by sending her dog familiar, Tatsumaki, to open up a portal on Earth while Cinque attempted to jump off from some heights in school (because of his love for circus acrobatic acts), and is the owner of one of Divine Swords pair, Excelide.

Seems to have fallen for Cinque at first sight, but was unaware that a summoned hero can't return to his homeworld and only found about that when it was too late.
