Aa! Megami-sama! (TV), Aria the Animation Recommendations
Both feature sweet, caring females in the lead. They are laid-back, with occasional moments of sxcitement, but generally are relaxing (sorta) slice-of-life animes.
Both shows deal with a very serene and joyful heroine surrounded by caring friends. Many episodes in each show are slice of life drama with the protagonists meeting new people and learning more about the world and themselves through these rewarding encounters. Both shows have gradual, but steady and meaningful character growth. And last but not least, the two sweetest & kindest Anime heroines you will ever meet, Akari (ARIA) and Belldandy (Ah! My Goddess), great protagonists!
