Set to cover the inaugural run of the advanced Tokyo-Osaka-Nagasaki Super Express train, Yuriko smuggles lppei along as her photographer. Unfortunately, instead of camera equipment, lppei grabs the wrong case from the office. Inside is a special compression unit containing an artificial life form, M1, that was to be transported to an Osaka lab, which ends up causing some trouble.

The police investigate a zoo where the cages were ripped open and find the zookeeper holding feathers and saying, "I saw a bird!" Meanwhile, Jun, Yuriko, and Ippei look into a strange ship. They find a bird but suddenly, the ship begins to sink and the bird goes to Saburo. At night, the bird he names Kuro flies out. Professor Ichinotani identifies it as Larugeus, a bird thought to be extinct.
