Satan gets unsealed, the king needs a hero, and he gets two guys who immediately start bickering about whether the tall one or the short one is actually the chosen one. The entire show is structured like someone compressed a fantasy epic into five-minute bursts and decided the real conflict isn't demons versus humans, it's these two arguing while stumbling toward the final boss. Every episode ends right when something ridiculous peaks, which means you're either laughing at the absurdity or genuinely invested in whether they'll survive their own stupidity. The comedy timing works because it never apologizes for being silly; it commits to the bit with the same intensity a standard shounen would use for an actual apocalypse. This is what happens when you take the hero's journey seriously enough to make fun of it properly.
A massive chasm tears open across the land, spewing forth hordes of demons. The king knows what this means: Satan Rchimedes, the ancient tyrant sealed away a millennium ago, has broken free. With no time to verify bloodlines or credentials, the monarch makes a desperate gamble, recruiting seventy-five candidates who claim descent from the legendary hero. Whoever brings down Satan first gets the glory and the reward. The problem is painfully obvious: most of these so-called heroes are completely useless. They're lazy, cowardly, incompetent, or some combination thereof. Two such misfits find themselves paired together, descending into the demon-infested underworld with nothing but their questionable skills and each other's company. What follows is a chaotic, hilarious descent where the real battle isn't against Satan, but against their own failures, each other's terrible decision-making, and the mounting absurdity of their situation. Expect crude humor, slapstick violence, and adventure that refuses to take itself seriously for even a moment.
