Six contestants compete in a high-stakes live TV quiz show to solve a complex "closed-circle" murder mystery for a 10 billion yen jackpot.

The story is about a young boy named Lubicchi and a trashman named Poupelle who meet on a Halloween night in a city that is full of tall chimneys. The chimneys pour out black smoke and the true sky cannot be seen.

When a massive, gilled monster emerges from the deep and tears through the city, the government scrambles to save its citizens. A rag-tag team of volunteers cuts through a web of red tape to uncover the monster's weakness and its mysterious ties to a foreign superpower. But time is not on their side - the greatest catastrophe to ever befall the world is about to evolve right before their very eyes.
