The Fog Dome. A zone cutoff from the rest of Tokyo. A world of madness and nightmare drenched in dense fog.

When scavenger Sousei Kanno takes a job to recover a sculpture from a mansion deep inside the dome, he expects to make an easy buck.

He doesn't expect her.

A girl chained to a wall. Across from her sits the cold body of a woman slashed to ribbons.

With black eyes and an empty smile, the girl tells him she's dead—a walking corpse bound to this mortal plane. She asks Sousei to find her killer and set her soul free.

Sousei's promise to help her pulls him into a murder mystery with more and more corpses, secrets better left unknown, and the truth behind the otherworldly Tokyo Fog Dome.

Will Sousei solve the mystery behind this living dead girl? Or is that which is dead better left buried?
