A kid gets blamed for every disaster caused by a troublemaking clay thing nobody else can control. The comedy lives entirely in that gap between what actually happened and who everyone assumes is guilty. Hanitarou Desu gets its entire energy from watching Yoshio take the fall, episode after episode, while the real culprit sits there looking innocent.
Yoshio's ordinary life takes an unexpected turn when a small clay figure mysteriously emerges from a sauceboat during dinner. The creature, who calls himself Hani Taro, becomes Yoshio's constant companion, though "companion" might be generous. Hani Taro lives for chaos: he steals food, breaks things, and creates trouble wherever he goes, yet somehow always manages to disappear before anyone catches him red-handed. The result? Yoshio gets blamed for everything. His family suspects him of pranks he didn't commit. His friends think he's lost his mind. Nobody believes that a mischievous clay imp is actually responsible for the mayhem that follows him everywhere. What starts as bewilderment slowly transforms into an odd sort of friendship. Yoshio can't get rid of Hani Taro even if he wanted to, and deep down, maybe he doesn't want to. Life was boring before. Now it's unpredictable, frustrating, and occasionally hilarious. Across seventy bite-sized episodes, this comedy mines humor from the simple premise: one boy stuck taking the blame for his impossible friend's relentless shenanigans.
