Akari Mizunashi

Akari is optimistic, curious and unusually receptive to wonder. She finds pleasure in flooded streets, changing weather, old buildings and chance meetings that other residents might pass without noticing.

Her sentimental observations regularly embarrass Aika Granzchesta, while Alice Carroll finds Akari's effortless ability to befriend people almost mysterious. Akari rarely seems conscious that she is doing anything unusual; she simply approaches strangers with genuine interest.

That openness extends to Aqua's supernatural side. Akari repeatedly encounters events connected to Neo-Venezia's cats and folklore, often accepting uncertainty rather than demanding a rational explanation.

Akari develops into a skilled gondolier under Alicia, although she does not begin as the strongest technical rower among her friends. Her initial self-training makes her extraordinarily proficient at rowing backward, a seemingly useless mistake that occasionally becomes a practical advantage.

Her strongest professional quality is hospitality. Akari remembers people, listens to their stories and can make passengers feel that they are discovering Neo-Venezia alongside her rather than receiving a rehearsed tour.

She also possesses an unusual sensitivity to the city's mysterious places and events. This is never presented as a conventional supernatural power, but it repeatedly brings her into contact with Cait Sith and experiences unavailable to most residents.

Akari's arrival on Aqua provides the central viewpoint through which Neo-Venezia is explored. Her Undine training gives her a reason to learn the city's waterways, traditions and people, while her curiosity continually carries her beyond formal lessons.

Her friendships with Aika and Alice form the younger generation's central training group. At Aria Company, Alicia's relaxed mentoring allows Akari to develop a professional style built around the qualities she already possesses.

Alicia eventually reveals that one of their ordinary-looking outings has actually been Akari's Prima examination. She promotes Akari and gives her the title Aquamarine.

Alicia's subsequent retirement leaves Akari responsible for carrying Aria Company forward. In later material, Akari becomes Ai's mentor, occupying the role Alicia once held for her.

Alicia Florence is Akari's mentor at Aria Company and the professional example she admires most. Alicia eventually promotes Akari to Prima and entrusts Aria Company to her.

Aika Granzchesta is the first close friend Akari makes on Aqua and her regular joint-practice partner.

Alice Carroll joins Akari and Aika's training group despite being younger and employed by another company. Akari's warmth plays a large part in drawing Alice out of her reserve.

Aria Pokoteng is Aria Company's president and Akari's frequent companion during her explorations of Neo-Venezia.

Ai Aino becomes Akari's regular correspondent after meeting her during a visit from Manhome. Ai later joins Aria Company as Akari's apprentice.

Cait Sith repeatedly appears during Akari's encounters with Aqua's supernatural side, seemingly watching over her.

Akatsuki Izumo befriends Akari and develops romantic feelings for her, although his attempts to express them rarely progress as intended.
