She also tends to go "Ehhhh?" a lot, especially in response to Aika's own admonishing Catch Phrase. Aika immediately knows something is wrong when Akira doesn't respond with that.
In one episode/chapter, Aika claims Akari tends to get distracted and say "Ah, suteki!" which means "oh, it's wonderful," or more contextually, "Ooh, that's neat!" but this isn't really shown in practice, though.
Does Not Like Shoes: Even though she has galoshes, Akari prefers to go barefoot when she's wading through the waterlogged streets, mostly because she enjoys the cold sensation of the water and the stone paving under her feet. Should one galosh slip off in the water, she's more inclined to pull the other one off and leave them off.
Friend to All Living Things: Not only does she befriend nearly every human she meets, but several animals and even a snow bug as well. She even feels sorry for some chocolate candies that won't get eaten because they got dropped onto the ground! Cranked up to eleven, even her gondola (in the form of an elderly man) put an umbrella over her, and if you believe her idea of who Cait Sith is, the entire spirit world of Aqua looks after her. In short, friend to all living things, and many NON-living things to boot.
Originally an anime-only character. Ai is Akari's customer in the first episode of the anime (in place of an old man in the equivalent manga story), and serves as the character that Akari corresponds with (in place of her unknown readers in the manga). Gets Canon Immigrant treatment in the last chapter of the manga.
Important Haircut: She used to have long hair, as she wanted to be like Alicia. However, it got burned, and she had to cut it short. At the same time, she realised it was better she was her own person, though she still looks up at Alicia as a role model.
One of the three Water Fairies, Aika's tutor. She's known by the title of "Crimson Rose" for her conversation skill with customers. Tomboyish enough that she can be considered as The Lad-ette (especially with Akatsuki mistaking her as a boy when they're children).
Hard Work Hardly Works: Averted. The only reason she's able to be one of the Water Fairies is because she works really hard. As she said, she has no notable talents like her friends Alicia or Athena have, so hard work is all she can do to make up for it.
The Lad-ette: Except the drinking part — she can barely hold liquor, especially compared to Alicia, who can hold massive amounts.
Cait SithMysterious Mega Neko that appears throughout the work, especially when the supernatural is involved, to Akari especially. Is the King of the Cats of Neo-Venezia, named after the king of the cats of Scottish folklore, and it is strongly suggested he is a guardian spirit of Aqua.
