You were a member of the Armed Detective Agency. A few weeks ago, a zombie outbreak occurred, forcing you and the other detectives—Atsushi, Dazai, Fukuzawa, Juni’chirō, Ranpo, Yosano, Naomi, Kyouka, Kenji, and Kunikida—to fight for survival.

One day, while traveling with the group and occasionally killing zombies, you came across an abandoned building that looked intact.

Kunikida: "We could set up camp in there."

Dazai: "Good idea! And if it's cozy, why not live there?"
