Fujiko Fujio's Dream Camera.

This is the first part of an omnibus TV drama special production starring three popular idols at that time, namely Nakayama Miho, Oginome Yoko, and Koizumi Kyoko. The stories, or mysterious events, all started with the revelation of the anomaly phenomenon by Horaguchi-sensei, the trio's physics teacher. The anomaly is due to the concurrent event of Hinamatsuri and the visit of Halley's comet to the inner solar system on March 3rd. Horaguchi-sensei teaches the class how to make use of the anomaly to unlock a mysterious event. This can be done by using any camera while chanting the specific keywords when pressing the camera shutter. From there, three separately mysterious events involving the three heroines began.
