Video Girl Ai

When Youta is told by the girl he likes, Moemi, that she likes someone else, he rents a video girl tape from a strange video rental shop. When he plays the tape at home, Video Girl Ai emerges from the screen to help him win Moemi's love. But Yohta's VCR had been malfunctioning and now Ai's personality isn't quite what it was designed to be.
