Aika M. Granzchesta | ARIA

The first friend Akari makes on Aqua, Aika is 16 when they meet. She is the only daughter and heir of Himeya Company's owners, but does not enjoy the distinction as she feels the company's employees fawned on her too much. Aika speaks bluntly and often responds to Akari's idealistic comments with "Embarrassing remarks are not allowed!". Despite their contrasting personalities, she gets along well with Akari and Alice, but frequently squabbles with her mentor, Akira, whom she resembles. 


Aika considers herself reliable, especially compared to distractible Akari and antisocial Alice, but both her friends call her a crybaby for her tendency to tear up when emotional. She is proud of her gondola skill as an undine, and can be very competitive about it. She also greatly admires Alicia, and finds any excuse to visit Aria Company and once tells Akari that if not for her family obligations, she would have joined Aria Company. Over the course of the series, Aika develops feelings for Al.When Aika becomes a Prima, taking the title "Rosen Queen" or "Queen of Roses". She takes charge of a newly opened Himeya branch office, in preparation for one day taking on the whole company. 
Aika was cosplayed by Uzuki, I'm not sure where Uzuki take this photo, but this scene looks too modern for ARIA, but overall good enough.

Akira E. Ferrari | ARIA

Akira is one of Neo Venezia's three Water Fairies, and is Aika's supervisor with the Himeya company. She is nicknamed the Demon Instructor for her strict training regimen as well as her loud and brusque personality. 

She is particularly harsh with Aika, in spite of the fact that the girl is her employers' heir, though she does so since she honestly thinks that there is potential in her. As such, she is the only Himeya employee who does not fawn on Aika, though even the latter admits that it is only due to Akira's strictness (and honesty) that she has been able to become a good undine. As a prima undine, she is known as "Crimson Rose".

Akira is famous for her conversational skills as well as her intimate knowledge of the sights to be seen in Neo Venezia. She has a lot of admirers among her customers, though surprisingly enough these are more female than male (which seems to bother her a little, as she considers herself very feminine).

Akira and Alicia's relationship mirrors Akari and Aika's, though Alicia is far more teasing when Akira is around. This isn't that much of a surprise, as Akira and Alicia are childhood friends. However, Akira is still galled that Alicia became a Prima earlier than her, despite the fact that Alicia initially became an undine to tag along with her.

Akira was cosplayed by GENRAI, very very matched cosplay!
