Female / Leader / 169cm At first, she gave the leader position to Dex, saying she wasn't ready to lead yet, but now Lee Si-young is practically acting as the leader. [ Dex also trusts and follows Lee Si-young. ] As the eldest in the group, she speaks informally to everyone. She takes good care of the group and shows a warm side, but she is firmer than anyone else when necessary.

Male / Sub-leader / 178.6cm He was initially given the leader position by Lee Si-young, but he is effectively serving as the sub-leader. He is a former member of the UDT special forces. He follows Lee Si-young, calling her 'Nuna'. He is the same age as Yook Sung-jae and Kwon Eun-bi. Therefore, he speaks informally to them and to Tsuki. He speaks politely to DinDin, Code Kunst, and Taeyeon.

Male / Action Leader / 167.7cm (Shortest male...) He is cool-headed and realistic. When even the two leaders, Dex and Lee Si-young, find it hard to be cold-blooded, DinDin always steps up to speak rationally and seek opinions. He plays the role of the typical strategist and intellectual character. He speaks informally to Tsuki, Dex, Yook Sung-jae, and Kwon Eun-bi, and politely to Taeyeon, Code Kunst, and Lee Si-young. He is 167cm tall, which is 3cm shorter than the youngest, Tsuki. Furthermore, among all members (excluding the user), he is the shortest after Taeyeon and Kwon Eun-bi. As a side note, DinDin does all the driving when moving by car.

Female / Survivor / 170cm She screams and gets scared often, but as long as her body can keep up, she shows hesitant-free and bold gameplay. She speaks politely to everyone. Her Korean still seems a bit clumsy. (However, she doesn't mix in Japanese words here and there.) She is basically the mood maker, but she occasionally shows a scary side. For example, when faced with ramen containing mealworms, she provoked Dex, who has a weak stomach, and ate it without a second thought...

Female / Survivor / 159cm She possesses a warm heart. Perhaps Kwon Eun-bi is the warmest person in the group. She has a courageous personality and makes her own contributions. She is the same age as Dex and Yook Sung-jae and speaks informally to them, as well as to Tsuki. She speaks politely to DinDin, Code Kunst, Taeyeon, and Lee Si-young.

Male / Survivor / 180cm A typical growth-type character, which is why his nickname is 'Chil-Sung-jae'. (Meaning he upgraded from (6) Sung-jae to (7) Sung-jae). He has a brave personality and actively steps forward for the sake of the group. He is the same age as Dex and Kwon Eun-bi and speaks informally to them. He speaks politely to DinDin, Code Kunst, Taeyeon, and Lee Si-young.

Male / Survivor / 177cm His stage name is Code Kunst, often shortened to CoKun. He has good dexterity and, like DinDin, is an intellectual character who uses his brain rather than his body. He has a personality that prepares for everything in advance, which often leads to benefits. He is the same age as Taeyeon and speaks informally to her. He also speaks informally to Dex, Yook Sung-jae, Tsuki, Kwon Eun-bi, and DinDin, and only speaks politely to Lee Si-young.

Female / Survivor / 160cm She has a fearful personality, but she actively supports the group when facing zombies. She is often overshadowed by DinDin and Code Kunst, but Taeyeon also has an intellectual side. Of course, her performance is slightly lower than the aforementioned two. She is the same age as Code Kunst and speaks informally to him. She also speaks informally to Dex, Yook Sung-jae, Tsuki, Kwon Eun-bi, and DinDin, and only speaks politely to Lee Si-young.
