OVA
Description
At fifteen, Akari Mizunashi departed Manhome (Earth) for the terraformed world of Aqua (formerly Mars), aspiring to become an Undine gondolier in Neo-Venezia. She trained with Aria Company, ascending from Pair apprentice to Single journeyman before earning Prima status through rigorous examinations, a milestone granting her the title "Aquamarine" or "Distant Blue" for her deep affinity with Aqua’s spirit.

Akari bears pink hair in short lengths accented by twin side ponytails secured with yellow clasps, and green eyes. As an adult, her hair lengthens—side ponytails loop upward while a single ponytail reaches her thighs. She perpetually wears Aria Company’s uniform: a seasonal white-and-blue ensemble featuring blue accents, yellow-lined boots, and a logo-adorned round hat. Winter variants include a cape, long sleeves, and gray tights; summer swaps in a cropped blouse and ankle-length dress.

Exuding exceptional optimism and perceptiveness, Akari uncovers wonder in mundane details through her "Akari filter," effortlessly befriending Neo-Venezia’s residents and visitors. Though her dreamy demeanor occasionally reads as airheaded, it sharpens her ability to spot overlooked subtleties. Mentor Alicia Florence deemed her "pure white," reflecting the world’s infinite marvels. Her speech peppers with signature exclamations like "Hahi" (yes) and "Hohe" (wonder).

Her career boasts unique rowing prowess: simulation training on Manhome gifted her extraordinary reverse-rowing skill, though she relearned standard techniques upon reaching Aqua. Key milestones include guiding first client Ai, who became her pen pal and eventual apprentice; transforming rivalries into friendships with fellow trainees Aika S. Granzchesta and Alice Carroll; and encountering mystical entities like Cait Sith, a benevolent giant cat who rescued her and remained a lifelong companion.

As a Prima leading Aria Company, Akari mentors Ai Aino—mirroring her bond with Alicia—while juggling heightened responsibilities that spark nostalgia for her trainee days. She embraces new everyday miracles in Neo-Venezia, sustained by enduring friendships. Her growth embodies legacy and continuity, evident while guiding next-generation Undines like Ai, Azusa, and Anya. Her foundational relationship with Alicia persisted, with Alicia noting Akari’s presence transmuted ordinary days into radiant, magical experiences.
