Manaka Junpei races to the rooftop of his middle school one day, only to be surprised by a falling angel - a beautiful girl wearing strawberry (ichigo) panties. Against the backdrop of a setting sun, she runs away, dropping her notebook. Junpei returns the notebook to the student whose name is listed in it, to Toujou Aya, but he is disappointed to find out that she is not the girl that he met on the rooftop.
