Akira E. Ferrari is a Prima Undine, the highest rank of gondolier, working for the Himeya Company in the city of Neo-Venezia on the planet Aqua. Born on July 29, she is twenty years old and stands 168 centimeters tall. She has long brown hair and chocolate-brown eyes, and wears the Himeya Company uniform with its red and white color scheme. Akira is recognized as one of the three legendary Water Fairies of Neo-Venezia, alongside Alicia Florence and Athena Glory, and is publicly known by her title, the Crimson Rose. She serves as the direct instructor and mentor to Aika S. Granzchesta, the young heir of Himeya, and her strict, demanding training methods have earned her the nickname the Demon Instructor. Despite her loud and brusque demeanor, she is deeply caring and principled, believing that success comes through relentless effort rather than innate talent—a philosophy shaped by her own experience of achieving Prima status through hard work. The origin of her title comes from a childhood memory in which a young Aika created a four-leaf clover by adding a rose petal to a three-leaf clover, inspiring Akira to compensate for any perceived lack of genius with determination. Akira shares a childhood friendship and friendly rivalry with Alicia Florence, and she is known for her exceptional customer service, encyclopedic knowledge of Neo-Venezia’s landmarks, and particular popularity with female customers.
