Saphir
Saphir is one of the twin princesses of Maasa, a water-based kingdom. She became the Ring Princess to secure the Ring of Water for Satou, allowing him to help save her country from the Empire's encroachment—and more importantly, to free her sister Saphira to be with Marse. She's now Satou's fourth wife.
Visually, Saphir cuts a striking figure: a slender woman with dark blue hair and a pair of forward-curving dragon horns. She typically wears a long white Roman-style gown with a flowing, frilly lower section, paired with gold arm bands and Roman sandals. She's notably flat-chested.
Her personality is where things get interesting. Saphir comes across as rude and blunt—the kind of person who says exactly what she thinks without filtering, and frankly doesn't seem to care what others make of it. But that's classic tsundere behavior: beneath the sharp exterior, she genuinely cares about people, especially her sister and Satou. Also like Granart, she's refreshingly unselfconscious about her body, showing zero embarrassment around Satou whether she's naked or wearing a revealing bikini.
