Juuni Taisen follows a brutal Zodiac Tournament held once every 12 years, where the deadliest mercenaries gather to fight under the names and traits of the 12 animals of the Chinese zodiac. In the blood-soaked arena of the twelfth tournament, strength matters, but so do deception, speed, and the ability to read an opponent before they strike. For every warrior, victory means the chance to claim a single wish; for everyone else, it means death.
The tournament begins in a desolate city that has been emptied of the half million people who once lived there, turning the battlefield into a silent graveyard. Before the fighting even starts, each contender swallows a poisonous gem, placing a hard limit on how long they can survive and making every clash even more desperate. As the Zodiac Warriors carve their way through the competition, alliances form only to collapse, pride turns into a weakness, and every encounter becomes a gamble with no safe outcome. Juuni Taisen is a savage battle of survival in which only one warrior can endure long enough to take everything.
