The Bodyguard

Nobita, Gian, and Suneo are playing soccer in a vacant lot. Nobita is about to score a goal, but misses and the ball falls into a puddle, splashing Gian, who gets angry and starts chasing it. When Nobita returns home, he watches a movie with Doraemon, where a male bodyguard protects a boy from two bandits. As soon as the movie ends, Tamako enters the room and asks Nobita to go to the store. Nobita himself asks Doraemon to help him protect himself from Gian. Doraemon takes out a figurine in the form of a yoshinbo from his four-dimensional pocket on his stomach. He inserts a coin into the figurine and tries it on Nobita. Nobita, although it was painful, took it with him so that he would always be protected from someone. Gian, who was guarding Nobita with Suneo, is about to beat him, but the yoshinbo pounced on them and hit them with a stick. Gian and Suneo take bats to hit Yoshinba back, but he hits them with a stick again. As soon as Nobita reaches the store and buys the goods, he meets Shizuka.
