ARIA is the story of Akari Mizunashi and her day to day life on Aqua as a Undine (gondolier). This is slice-of-life anime at its best. The series started out as a manga and has been translated into animated form beautifully. The stories tend to be fairly simple glimpses into Akari's life. Wether it is giving a free ride to a young girl and showing her what is special about Aqua or practicing her rowing with her friend Aika. You always find a relaxing bit of story. So far, one I'll be watching.
