Juni Taisen: Zodiac War Vol. 3 (manga)

With half of the fighters down for the count, the Zodiac War rages on! Usagi--the fighter of the Rabbit--and his undead army continue to rampage across the battlefield, intent on destroying anyone who stands in their way. For an honorable fighter like Ox, Rabbit's desecration of and complete disregard for human life is unacceptable. To obliterate this heretical army, Ox teams up with an unlikely ally--the drunkard Tiger!
