In this anime, I recall there being little people (toy dolls, perhaps) that could be bought in stores. If you put on a certain headset, you could move them around and play with them. There were competitions that you could enter these dolls in.
The main character is a girl, who has friends who enter the dolls in competitions. In addition, there is a male character (who may have had black hair, though I'm not certain). He enjoyed reading, and in either the opening or ending song, he could be seen falling asleep on his books.
What is the name of this anime?
