A highly anticipated cultural festival is less than a week away for the students of a local high school when mysterious, seemingly paranormal events start occurring within their building. A piano plays when no one is in the room; the power continually shuts off, seemingly at random; footprints are left behind by an unseen presence; objects appear to levitate and are hurled across the room. Concerned about the strange phenomena, six students, advised by Professor Yamakawa, form a research team and investigate the strange goings-on. One of the students is Reiko Kudo, who has ESP and a family history with the occult. As the investigation ensues, a disturbing story from the past emerges from the woodwork, culminating with an ESP confrontation on the day of the festival...

High school student Mikiko travels back in time to the future using a time machine built by Monjiro, the physics club advisor. What awaited her there was the reality that her best friends, Yoko and Tatsuro, were already married and were on the verge of breaking up. Mikiko returns to the modern world with the help of future Monjiro to mend their relationship.
