Its their first year at Honcho Junior High and things get off to a very shaky start when students left and right begin having strange experiences. While Miyuki visits her teacher Saeki to attend to a finger cut, she has visions of a somber-faced girl in an outdated school uniform. At that very moment, panicked students run into the office announcing that another student, Mizudani Sachie, has fainted while in the "Hanako stall" of the girl's bathroom, the rumored location of the haunting spirit of a young girl. When Sachie fails to regain consciousness, she is taken to the hospital, where she later awakens with no memory of the incident. Upon her return to school, however, Sachie now seems to have full insight into other things such as the manner of death or serious injury each student will face.

First-year junior high students Mai and Miyuki naturally huddle together during their transitional year from classmates of elementary school. Once in their more metropolitan junior high school, however, they are soon introduced to a wider and more exciting exposure to the world. On the positive side, this includes independent ventures into the more culturally notorious elements of Tokyo such as Harajuku with slightly drunken upperclassmen. Unfortunately it also involves being thoroughly initiated into their new school's rumored history of an omen-filled death three years prior on the school's rooftop and stories of hauntings by the ghost of a young girl.
