Mahou Shoujo Ai  

In a particular town, there were a series of mysterious attacks that led people to believe they were caused by supernatural entities such as ghosts. The students in Akitoshi's school were scared because of these incidents. One day, an unknown girl appeared at the school, but only Akitoshi thought he didn't know her before. He followed her to investigate and lost sight of her. Then, while searching for her, he heard a woman scream from a nearby material yard. Upon finding the source of the scream, he discovered that Mikage, a beautiful girl from his school, was being attacked by monsters called "Yuragi." Yuragi recognized Akitoshi and began attacking him. Suddenly, Ai appeared and defeated them both. Akitoshi looked at Ai in astonishment. What is her true nature, friend or foe?
