Aika S. Granzchesta

Aika is the heiress to the Himeya Company. The first friend Akari ever made on Aqua, Aika is an Undine for Himeya, the oldest and currently second-ranking water-guide company in Neo-Venezia. As the only daughter of its owners, she is also Himeya's heir, but does not enjoy the distinction that much, as she feels that she is fawned upon too much by the company's employees. Aika wears the red and white Himeya undine uniform, and matching earrings. She has brown eyes and long dark blue hair braided in pigtails, which goes down to her mid-thighs. Later on, a large part of her hair is burned and after having a talk from Akira, she decides to take on a new haircut. She now has a pixie cut with four hairpins on the left side of her hair. Aika often speaks in an open and blunt manner, and goes out of her way to cut off Akari's many idealistic comments with a preemptive "Embarrassing remarks are not allowed!", Hazukashii serifu kinshi!). Aika openly fawns over her idol Alicia, but secretly treasures the care of her mentor Akira.
