Juuni Taisen
十二大戦
Rampage. Weep. Kill. Every 12 years, the 12 signs of the Chinese zodiac take the form of warriors and engage in the ultimate battle royal. They face one another in battles to the death, using all the powers of their star signs, and the sole survivor is granted the ultimate prize—a wish. Any wish.
Juuni Taisen is an adaptation of Nisio Isin's novel of same title.
