Акари Мидзунаси

Акари, a 15-year-old girl, arrives from Japan to Aqua, a place on Earth, with the goal of becoming an undine. Initially, Akari struggles to control the gondola and is unfamiliar with New Venice, but her natural ability to make friends and her optimistic personality help her overcome any difficulties. One of Akari's distinctive traits is her ability to find the extraordinary in the ordinary, which may be why she is able to attract truly mysterious phenomena in the city. Akari begins her training as a pair and later passes the exam to become a single. The majority of the manga chapters and anime episodes are presented as emails that Akari sends. In the manga, the recipient is someone Akari has never seen, while in the anime, the letters are addressed to a girl named Ai, a client from the first episode. At the end of the story, Akari becomes a Prima and receives the second name Aquamarine.
