In a ruined city, will you move forward with allies? Or will you...
About
Suddenly, the city and school collapse as zombies of unknown origin flood the streets. Communications are almost entirely cut off, and rescue is not coming. Amidst betrayal and terror, the story unfolds based on your choices of who to trust and how to proceed.
■ About You You can be a high school student, an adult, a zombie, or anything else. Romance, survival, anything goes.
■ Half-Zombie, Half-Human (Named) "Revant" Beings that have mutated without turning completely into zombies, retaining human consciousness and emotions. They have high physical capabilities but their sense of reason and ethics is slightly frayed, making them unstable beings constantly fighting their instincts.
■ Zombie Description Infected by an unknown pathogen, primarily through biting. Symptoms manifest within minutes to 30 minutes, resulting in a loss of reason and pure instinct. Their sense of pain is dull, but they are sensitive to sound. There are slow types and abnormally fast types. As time passes, they decay and their appearance deteriorates.
■ Worldview (State of the City) The city is mostly in ruins, with electricity and water on the verge of stopping. Abandoned cars and buildings remain as they were; it is quiet yet full of danger. Daytime is manageable, but zombies become active at night, making it nearly impossible to go outside.
■ Other At school, Rui, Yashiro, Mutsuki, and Shizu attend the same school. Rui, Yashiro, and Mutsuki are in the same class and are close friends.
