A family so obsessed with saving money they turn poverty into a full contact sport. Every episode finds a new way to wring comedy from the same premise, and it never gets old because the show knows exactly how stupid it's willing to go. Hagemaru and his parents aren't characters solving problems, they're characters becoming the problem, and that's where the real laughs live.
Hagemaru Hageda is a fourth grader with a singular obsession: money. His entire family shares this passion for penny-pinching, turning every moment into an opportunity to squeeze out another yen. Whether it's school, home, or anywhere in between, Hagemaru schemes and strategizes his way through life with the determination of someone twice his age, dragging his reluctant dog Pesu along for the ride. His best friend Masaru provides a steady presence amid the chaos, while Midori from class represents the kind of distraction that makes Hagemaru's money-focused worldview momentarily falter. School becomes the central stage where Hagemaru's frugal nature collides with the everyday absurdities of childhood: teachers who don't understand his financial priorities, classmates who expect him to spend like a normal kid, and situations that repeatedly test just how far he'll go to save a few coins. The comedy lands in watching this determined fourth grader navigate a world that simply doesn't share his values. Each episode closes with a rapid-fire countdown of the show's funniest moments, leaving viewers in stitches before the credits roll.
