The 3rd episode of Juni Taisen Zodiac War - Cutting a Chicken with a Beef Cleaver
One of the Warriors have been killed and it was the Rooster. Explaining the Rooster: Niwatori (Rooster), real name Ryoka Niwa. Kills them by Pecking.
As Chicken retrieves the gem from inside Dog's body she recalls her earlier life as an abused child who killed her parents. She suffered from severe amnesia but showed an ability to communicate with birds. She was then taken in by the Niwa family who turned her into a killer who carried out their instructions without conscience. In the present, she instructs her birds to attack Boar, and although many are killed, they eventually prevail and devour her body. In the subway tunnel, Ox relentlessly attacks Horse who has an iron-like skin. In a convenience store Chicken meets Rat who offers to take her to Monkey. Chicken follows him into the underground sewers, calculating when she should make a move to kill them, but she is uncertain of Monkey's motives. Eventually she leaves, wondering why she did not kill them. She realizes that the enhanced power from the Dog's bite has also made her more sensitive. As she walks, engrossed in her thoughts, she encounters a blood-stained Ox. Unsure of whether to fight him, he attacks first and kills her, retrieving both the Chicken and Dog's gems. As she dies, she gives her birds permission to feed on her body.
