- Asami Nakaoka (中岡 あさみ Nakaoka Asami?)
- A young traffic enforcer, Asami is in charge of guarding the Mall and protecting the group of survivors sheltering there. She also speak in a third-person speech pattern, such as replacing "I" in her sentence with her name instead, though this is because police in Japan refer to themselves in the third person (though she has yet to master this). Easily scared and intimidated by others, Asami's authority quickly waned amongst the survivors until Kohta and Takashi intervened by handing her a standardized police firearm and building up her confidence. She developed a liking for Kohta after he helped her subdue a civilian who was about to sexually assault Shizuka. Asami later accompanies Takashi to help obtain blood plasma for a sick survivor, and is forced to mercy kill Tamaru when he is bitten by "them". Asami firmly believed that her superior officer, Matsushima, who had left for the police station for help, would come back until she is shocked and horrified to see a zombified Matsushima walking towards the mall, utterly shattering her self-optimism. After running to the mall's roof while she was greatly upset, Asami was kindly praised by the same old couple that she helped in helping the old woman in having the blood transfusion, allowing her to rekindle her spirit. Asami is encouraged by Kohta into coming with him and his friends, which she gladly accepts.
- Shortly after breaking out of the mall with the group she attempts to save a frightened student trapped in the parking lot. Despite distracting the zombies long enough for the student to escape Asami herself gets trapped whilst without any means of defending herself. As a nod to upholding her duty as a police officer she sacrifices herself by further drawing the attention of the zombies so the group can escape. Asami shouts out one final request for Kohta to not let her get turned into a zombie as they slowly converge on her. She is last seen tearfully confessing her love to Kohta while saluting as he aims his gun sight on her from a distance. It is revealed in the following chapter that Kohta killed her (as per her request that she die human and not turn into one of "them"), leading to him experiencing a mental breakdown.

Yuriko Takagi (高城 百合子 Takagi Yuriko?)
Voiced by: Yoshiko SakakibaraSouichiro's wife and Saya's mother. Yuriko was once a New York Stock Broker who later married her future husband after she was impressed with his charisma and political skills. Thanks to her business connections, the Takagi family fortune rises significantly. She is very faithful to her husband and loves her daughter very much. She was last seen with her husband and other survivors fighting against the horde that breach their estate.
- Souichiro Takagi (高城 壮一郎 Takagi Sōichirō?)
- Voiced by: Jouji Nakata
- Leader of a radical Uyoku dantai group in the Tokonosu district, he is an extreme right-winger who showed his leadership to the survivors when he rallies them to kill the zombies in order to save Japanese society from collapsing. He added a rather pointed illustration by killing his zombified subordinate. Later on, he insists that Kohta give up his weapons. However, Kohta's friends (including Saya) rallied for Kohta and supported him. It is implied that he was impressed by their willingness to challenge him and allows Kohta to maintain the weapons he took from Rika's house.
- It is also shown that Saya hates her father more than her mother because he didn't ensure her safety when the outbreak started in Japan. Souichiro seems to be a sword expert and is skeptical about Hirano's reasons of keeping his guns until he's confronted by everyone in the main group except for Marikawa, who defends his reasons for protecting his daughter. It is currently shown that he and his followers are preparing to leave the estate in two days time and is told by Takashi if he and his friends are not back with their parents by then, they should leave without waiting for them. However, when the zombies manage to enter the estate due to a gap from one of the barrier's inadvertently created by Shidō, the Takagis, their followers, and the remaining survivors fight to hold off the invading horde until they could go to other areas of the neighborhood that were not breached. Before Takashi & his entourage leave the estate, Kohta and Takashi swore to Saya's father to protect her and Saya tells her parents that she loves them before they attempt their escape. Souichiro and his wife were last seen fighting against the horde with rest of the estate survivors while saying that they were proud of their daughter and the friends she made. Their fate is currently unknown.
Hisashi Igō (井豪 永 Igō Hisashi?)
Voiced by: Mamoru Miyano[1]Rei's classmate and boyfriend, he, Takashi, and Rei were among the first to try and escape the rampage at the school. On their way out of class he was bitten by an infected teacher and subsequently turned into one of "them" afterwards. Aware of his fate he instructed Takashi to kill him before he turned by throwing him off the rooftop of the school building, but died before Takashi could do so, and rose back up as one of "them". Takashi then gathers himself together and takes down Hisashi permanently. A brief bitterness between Rei and Takashi occurred as a result from his death. He was thought to be one of the main characters of the manga because during the first chapter being the cool calm headed leader type of character. Hisashi was responsible for "naming" the zombies as "them".
