Over Image

In a world entirely devoid of color, Sai, a young man, finds himself in an unfamiliar and strange environment while on his way to school. There, he observes a confrontation between two girls—one he recognizes as Mikage Mikuro, a senior from his high school, and another he has never met, a blonde girl. Later, this girl appears at Sai’s school as a new transfer student. She has joined the competitive game "Over Image" to fulfill a personal goal and now approaches Sai, asking if he is an adversary or an ordinary person.
