A girl named Chiaki returns to Japan from America and enrolls in an all-female school. She recalls stories from her late brother about a "Snow Black Princess" in a magical realm. Two upperclassmen attempt to install a program called Brain Burst on her, but she refuses. It is later revealed that her brother had installed it on her three years prior, making her an unconscious participant in the program.
