This is an elementary school version of Mr. Kinpachi in Class 3B. Gansuke (Kishitani) is an elementary school teacher from Hokkaido who moves to Tokyo to be near his sweetheart Masako (Tokiwa), who wants to become a hairstylist. He is the home room teacher for 4 nen 3 gumi. You see the elementary school setting in a different way and laugh at the same time.
