Pitaten is an anime and manga series. Originally written by Koge-Donbo, it was adapted into an anime by Akemi Menda and Yasuko Kobayashi that was aired by TV Tokyo on April 7, 2002.
The plot focuses primarily around Misha and her attempts to become a licensed angel and Higuchi her neighbor. It is generally light humored, but the ending of both the anime and the manga was concerned with dealing with the death of loved ones.
I love the series Pita Ten, it is so cute.
The title, 'Pita Ten' is short for 'Pitari Tenshi', which literally means 'clinging angel' in English.
