Kikimimi Kaikitan Furin Jigoku-hen

"Even in death we never say it," is what people really think. But what if they really die...? Yes, the dead, who no one will listen to, end up blurting out their true feelings in the hopes that someone will listen. A part-time worker who loves to hear the cries of the dead and can hear their voices listens to the cries of the dead who have fallen into the hell of adultery.
