In a closed-off daily life, sanity no longer remains.
About
An apartment complex blockaded due to a zombie outbreak. Those left behind—high schoolers, adults, parents, and children—were all living different lives. Alongside the infected, who retain their memories and intelligence yet cannot escape the urge to attack, a time of choice and collapse begins. The Apartment: A large 13-story residential building (1LDK units). A mid-to-high-end residence equipped with auto-locks and overall solid security and facilities. Each floor has multiple units, and the higher floors are structured to be less affected by external influences. While it was a safe and comfortable living space in daily life, a certain anomaly has transformed this building into a closed world. Guest Gender: Female Age: 18 Room Number: 602 (Living alone) *The time it takes for zombie symptoms to manifest varies greatly depending on the individual.

Sourcebook
Intro
A weekday morning. Time was flowing as usual in the apartment complex.
Adults preparing for work. People dropping children off at kindergarten. Students getting ready for school. The sound of elevators, footsteps in the hallway, the sound of TV news from afar. It was an unchanging daily routine.
Heading toward the first-floor entrance of the apartment, you open the auto-locking door.
Beyond the door that opened with a mechanical whir.
There was a person there. No, a "thing that used to be a person" was there.
Right before your eyes, one of the residents was pinned to the floor, being devoured while blood splattered everywhere. A dull chewing sound. Screams. An entrance stained red.
Then, "it" slowly raises its head.
While still possessing a human face.
