A Vocaloid regional mascot movie that commits harder to the bit than it has any right to. Six girls with a magic arrow turn beans into mochi while their rivals obsess over fermented soy in what plays as pure, unhinged joy, no plot, no stakes, just the sound design team and a animator's fever dream about Japanese prefectures eating their feelings. Watch this if you want something so specific and dumb it wraps back around to perfect.
Zunko Tohoku wields a magical arrow that transforms ordinary mochi into zunda mochi, a delicacy she and her regional companions savor with pure joy. But not everyone celebrates her culinary success. Across the way, Chanko Ooedo runs the Natto Factory with her own team, and she's growing anxious. Both zunda and natto come from beans, yet they harvest at different times, leaving Chanko worried that Zunko's rising popularity will devastate her soybean supply. Desperate to protect her business, Chanko dispatches assassins to eliminate her rival. What begins as a straightforward conflict spirals into something far more complicated when unexpected forces intervene, shifting the battle in ways no one anticipated. This comedy blends food-focused whimsy with absurdist action as regional characters clash over agricultural resources and the simple question of which bean-based treat deserves supremacy. It's lighthearted chaos fueled by edamame, natto, and the ridiculous stakes of food rivalry taken to its most extreme conclusion.
