The first two episodes kill someone you thought mattered, then spend the rest of the show proving you were wrong about who deserves to live. Twelve warriors with zodiac names fight for one wish, but the real war is the one happening inside your head as the show systematically dismantles your read on who's actually dangerous. Each character backstory hits different once you realize the tournament isn't about winning, it's about what you're willing to sacrifice when immortality is on the table.

Twelve warriors bearing zodiac names enter a competition held once every dozen years. The prize: a single wish, no matter what it is. These aren't ordinary fighters. Each is a formidable mercenary who carries the name and traits of one animal of the Chinese zodiac, from Rat and Ox to Dog and Pig. The twelfth tournament opens in a deserted city whose half million residents have recently vanished without a trace. Before the fighting starts, every competitor swallows a poisoned gem, so both the contest and their own lives are on a clock. The battlefield becomes a place of conspiracy and murder, and the combat continues until a single victor is left standing. Twelve enter. One leaves.
