Angela Victoire Blendin
One of the competitors in the Princess Waltz, hailing from the land of Agnis. Also known as the Dragon Princess, a name which fits her proud and domineering personality. Her natural elegance is balanced against equal measures of self-satisfaction and lascivious speech.
Liliana Lun-Lun Guenther
The Storm Princess of the ocean kingdom of Renstanza, and a competitor in the Princess Waltz. She's a high tension character, a pleasure seeker always in good spirits. Battle should be flashy and fun is her motto, but she's incredibly serious about her participation in the Waltz.
The Princess of Steel from Palmied, country of blacksmiths. She fights to prove that her own personal dress is the strongest. Uninterested in matters beyond smithing, she doesn't get along well with those beyond the inner circle of her artisan comrades.
The hot-blooded and impulsive hero of our story. An all around good guy with a positive but rather simplistic worldview, he is quick to rush to the defense of those he sees as wronged. He values friendship highly, but turns a blind eye to romantic entanglements unless they are thrust upon him.
The daughter of Fukamori Nanae, and Arata's foster sister. Raised together since they were small, despite the lack of a blood connection their relationship is that of true siblings. She acts as his mentor in many ways, a strong and serious presence more like a samurai than a traditional Japanese beauty.
