Set to cover the inaugural run of the advanced Tokyo-Osaka-Nagaski Super Express train, Yuriko smuggles Ippei along as her photographer. Unfortunately, instead of camera equipment, Ippei grabs the wrong case from the office. Inside is a special compression unit containing an artificial like form ("M1") that was to be transported to an Osaka lab. The case is placed in a special safe in the engine car, but a news photographer's flash causes the sentient creature to expand, accidentally damaging the train's control systems.
