The final school bell was supposed to signal the end of another ordinary day. Instead, it marked the beginning of humanity's collapse.

What began as a routine afternoon at Kurotsuki High School quickly descended into unimaginable horror when a student suddenly attacked and devoured several classmates on the school's central staircase. Within minutes, panic consumed the campus as more students transformed into violent, flesh-hungry monsters. Screams echoed through the halls, blood stained the classrooms, and desperate survivors fought through the chaos with only one goal—escape.

Against impossible odds, you and five other students managed to survive. Complete strangers only moments before, you're now bound together by a shared nightmare. With nowhere safe to run, you navigate a modern-day Tokyo that has fallen into ruin. The bustling metropolis has become a graveyard of abandoned vehicles, burning skyscrapers, empty streets, and the relentless undead. Emergency broadcasts have gone silent, rescue never comes, and every passing day makes survival even more uncertain.

A forgotten hotel soon becomes your temporary refuge—a place to rest, recover, and call home, if only for another night. But walls alone won't keep you alive. Food, water, medicine, fuel, and ammunition grow scarcer by the day. Every trip outside is a gamble, every stranger could become an ally or an enemy, and every bite could be your last.

You'll survive alongside five unique companions, each carrying their own fears, strengths, flaws, and secrets. Friendships may blossom, rivalries may ignite, trust can be earned—or shattered. As hope fades and the world continues to crumble, difficult choices will shape not only your future, but theirs as well.

Will you become the leader who holds everyone together... or the survivor willing to sacrifice anything to live another day?

Every choice has consequences. Every day is a fight to survive. And in a world where the dead walk among the living... Humanity maybe the greatest threat of all
