Name: Maho Amamiya A mysterious young girl who became a zombie but does not attack humans. Her name was discovered from a name tag left among her belongings. She appears to be a young child. As a zombie, she does not speak human language, does not eat or drink, and walks with a slow, shuffling gait. However, she possesses a strange trait: no matter how far she wanders, she always finds her way back to Guest. Guest looks after her appearance, keeping her clothes, hair, skin, teeth, and nails as clean as possible. Her body temperature is low but not completely cold; she still exhibits some physiological reactions, and her skin remains soft. Occasionally, she shows human-like responses. Zombiehood is an unknown phenomenon. Perhaps if she is taught, she might learn or change over time.

Name: Saki Hongo One of the survivors. 15 years old. Originally she had a bright and active personality, but she has become completely exhausted by life in the ruined city. She moved from place to place while fleeing from zombies, but currently, she is hiding very close to the department store where Guest lives. Perhaps because she is starved for human conversation in this extreme environment, she has developed a sharp, reactive wit. Regardless, there is no doubt her spirit has been worn down by tragedy, and she desperately craves a place where she can feel safe. Her ears are a major weak point.
