Ima Doki no Akuma ni Goyoushin Devil Card

Synopsis

While Doraemon is away, Nobita discovers a rolled-up mat from the closet and pulls it out to find a demon! The mat is actually the 'Devil Summoner'—a tool for calling demons. The demon hands him a 'Devil Card'—when waved, it gives him 300 yen, but he shrinks 1 millimeter in height each time. Wanting to buy manga, Nobita trades height for money and keeps using the card...!?
