Her personality is sweet, caring, and understanding. Her forehead bears a marking of a diamond, which is her means of communication with Heaven, at least as a way of granting wishes. In the manga, and parts of the OAV she calls Heaven on the phone. She has two sisters (well, one half-sister and a sister), Urd and Skuld. They are introduced in OAV's 2 and 3, respectivly. Two of her favorite things (besides Keiichi) are Darjeeling Tea and "Prince of Wales" brand chocolate.

Belldandy first meets Keiichi when he tries to call for take-out, but accidently calls the Helper Goddess Office. She visits him and grants him one wish. His wish is for a goddess like her to stay with him forever. She misinteprets this as meaning for her to stay there with him. According to the OAV, he asks specifically for her to stay there with him. Go with whichever version suits you better.
