Ringo Tatsuki belongs to the Tasuki House of Jurai's Royalty, distinguished by long wavy pink hair with red side accents and vivid emerald eyes, typically adorned in a blue-and-white dress. She originates from a sizable family and maintains a close bond with at least one admiring younger sister. Professionally, she commands Jurai's accounting division, wielding formidable authority over the empire’s finances. Even powerful figures like Seto Kamiki Jurai tread carefully around her during monetary discussions, acknowledging her reputation as "terrifying" in fiscal matters. Her financial stewardship includes managing galactic rewards from Seina Yamada's pirate captures, allocating planetary-scale budgets to him—though Seina remains unaware as Kiriko controls his funds. Ringo further shields Seina’s family business from predatory corporations, using his accrued interest to expand their enterprise. Personally, her feelings for Seina deepened after a trip to Imu, where pheromones and shared responsibility for the infant Mikage intensified their connection. Typically, Ringo exhibits delicate, polite manners consistent with combat-trained Juraian royalty, contrasting sharply with her intense financial persona. Her life features absurd mishaps, like being twice knocked out, boxed, and mailed—first by Kiriko to prevent Seina meeting her, then by Seto as a faux vacation. Later, Otoka Masaki joins her team as assistant following Mizune Masaki’s abandonment of duties.
