Anastasia to Otonari

Overview

Five-year-old Anastasia lives with her father, a writer, and their housekeeper. One day, Ursula, a blonde woman with glasses, and Oliver Klum, an unidentified two-dimensional creature (?), move in next door. These neighbors are very mysterious people, and with a snap of their fingers, cats and pots fly through the air. Papa, who was so busy with work that he had forgotten Anastasia's birthday, was admonished by Ursula and reminded of the importance of spending time with family. Note: Also includes the one-shot stories Tulip Carnival (チューリップ・カーニバル), and Margaret-sou no Roufujin (マーガレット荘の老婦人)
