Zero, is a mixed-breed puppy that joins the group when Takashi rescues Alice. He is named after the Mitsubishi A6M Zero fighter plane, which was also nicknamed Zeke by the Allied forces during World War II. Soichiro Takagi is Saya's father. He is the leader of a right-wing nationalist group in the Tokonosu district. He showed his leadership to the survivors when he rallies them to kill the zombies in order to save Japanese society from collapsing, and publicly kills his zombified subordinate. Soichiro seems to be a sword expert: he prefers to use the sword instead of his wife's Luger P08 pistol and has trained with Saeko Busujima's father.

Asami Nakaoka is a young traffic enforcer for Tokonosu Higashi Police Station; she guards a group of survivors at a nearby mall. She refers to herself in the third-person.
