Айно Ай

A girl from Man-home. Initially, Ai came to Aqua to explore in a rather negative attitude because her elder sister often boasted to her how good Aqua is, only to find that it was boring. However, meeting & befriending Akari & friends changed Ai's mindset. Ai became the recipient of Akari's letters, and through Akari's mails, Ai started to love Aqua more than ever. Whenever time permits, Ai would pay a visit to Akari in Aqua. She eventually joins Aria Company a couple of years after Akari becomes a prima, thereby becoming Akari's student.
