A thief dies for two centuries and wakes up as a wind-up corpse forced to do good deeds with a dumpling sword. The premise is absurd enough that it commits completely to the bit. Every episode runs on the logic that if you're going to be trapped in a redemption loop, you might as well fight monsters with skewered food while cracking jokes about your own death.
A clockwork samurai wanders a peaceful village armed with an unusual weapon: a sword strung with dumplings. Two centuries ago, Zennosuke was a petty thief who met an untimely end, only to be pulled back from death by divine intervention. His resurrection came with a catch. A wind-up key embedded in his skull keeps him tethered to life, but it only winds forward when he performs acts of kindness. Without regular good deeds, the key stops turning and so does he. Now Zennosuke moves through town resolving conflicts the only way he knows how. When anger flares or greed takes hold, he draws his peculiar blade and sends dumpling projectiles straight into the mouths of those who've lost their way. Something about the warm food sparks a change in people's hearts, softening their hardened edges and reminding them what matters. Each small victory sends a rainbow across the sky and keeps the key ticking. It's comedy born from absurdity, where a sentient dessert weapon solves human problems one chopstick at a time.
