Every 12 years, a group of elite mercenaries with exceptional strength, intelligence, and precision come together for the Zodiac Tournament. Named after the Chinese zodiac animals, each warrior fights fiercely in a deadly competition where only one can emerge victorious. Set in a barren city that once thrived with half a million inhabitants, the 12th Zodiac Tournament takes a dark turn as each fighter swallows a lethal gem, ticking down the time left in the tournament and in their own life. With a single wish awaiting the ultimate champion, the Zodiac Warriors dive into a brutal and high-stakes battle for their survival.
