An unusual number of people have suddenly lost consciousness at a hospital and all of the victims are young females who all said something about wanting to be with someone named Sho. However, no trace of Heavy Acceleration has been found. A mysterious patient with no matching record has surfaced and she is identical to Medic, most likely being her copy model. Shinnosuke starts the investigation based on the Sho testimonies.

Shinnosuke un-transforms and questions Medic about the reasons behind her actions. Medic, not knowing what her true love for Heart means, decided to respond. What came from her mouth was the secret of the day the Global Freeze happened a year ago, the same day the Medic that looks like Misuzu Hatori was born. Meanwhile, Banno, now having succeeded in becoming Gold Drive, targets Medic again. The Promised Number is 4 Over Evolved Roidmudes. Counting Gold Drive, who already has the power of a Over Evolved Roidmude, if Medic Super Evolves, they will be complete. Banno goes into action to trigger her evolution.
