Nobita wants to buy a manga book and asks for an advance on his allowance, but his mom firmly refuses. Unable to give up, he tries to secretly get the money early, but gets scolded and becomes discouraged. Frustrated, he decides, “If that’s how it is, I’ll just become a total villain!” and takes the “Devil’s Passport” from Doraemon. It is a terrifying passport that allows him to get away with any wrongdoing. Freed from being scolded, Nobita begins doing only bad things (like kicking empty cans and trash bags) taking advantage of the fact that no one can punish him.

Even though it’s his birthday, Nobita feels disappointed because he worries his parents’ present will once again not match what he wanted. Trying to distract himself, he visits Shizuka’s house, but while waiting for her to return, he becomes impatient and asks Doraemon for a way to skip wasted time. Doraemon then introduces the “Time Warp Reel,” a gadget that allows them to jump forward in time, leading Nobita to experiment with fast-forwarding to the moment Shizuka comes home.
