For one wish, they’ll risk it all. The time has come for the Twelve Tournament—held every twelve years. Twelve proud warriors, each bearing a name from the Chinese zodiac, will prepare to fight in the bloody battle royale. The victor is granted a single wish, and they’ll do whatever it takes to earn it. Blood and tears will flow on this battlefield—who will be the lone survivor?
