|“||You survived just by chance.||”|
Shiiko Aosoi (青襲 椎子 Aosoi Shīko ) was a lab technician at Saint Isidore University. Her whereabouts makes her quite mysterious since she has been locked inside the chemistry labs.
She has long light colored hair and wears an unbuttoned lab coat which covers a lined turtle-neck sweater. She is usually smoking a cigarette.
Aosoi is socially awkward and prefers to keep inside and in front of her computers, rather than go outside talk to people face-to-face. Once she meets the cast, she regularly gives other characters uncomfortable stares and replies to questions with blunt remarks. She does not care about invading the personal space of others, and is quick to declare that Kurumi is infected, regardless of what others might think. She is shown to have no remorse or problem with killing zombies at close range, using a hammer and screwdriver.

She seems to be the remaining surviving staff member of the University and has kept her existence hidden from the Melee Fight Club and Fallen Crew so as to not be dragged into their conflict. She has been secretly researching some imprisoned zombies in her chemistry lab in order to find out more about the infection, but reveals her existence and continuing research discreetly to Miki over the intercom when she came exploring.

- Even though her name has not been officially revealed on-page, Miki directly calls her "Aosoi" over the intercom in chapter 50.
- Aosoi speculates that the zombie infection was caused by a large-scale, pre-planned aerial attack; with the survivors being temporarily immune to it.
