When young Akiko marries mystery author Masakazu Isshiki and moves in with him in Kamakura, her way of life becomes a constant source of amazement. A simple stroll through the streets brings her into contact with supernatural creatures such as spirits, goblins, ghosts, and not-grim-at-all reapers. As Akiko learns very quickly, Kamakura is a place where humans and non-humans live side-by-side in harmony.
The Isshiki residence is also home to a parade of other distinctive denizens, such as Kin, a maid who may actually be 130 years old; Masakazu's incorrigible editor, Honda; and even a poverty-attracting entity. Although Akiko's newlywed lifestyle isn't quite as she'd imagined, it still turns out to be a lot of hectic fun.
One morning, Masakazu awakes to find that Akiko has disappeared. The only trace of her is a loving letter to her husband... It seems that Akiko has met an unfortunate accident, died, and departed for the netherworld. Upon losing his wife, Masakazu realizes for the first time how much he loves her. To bring Akiko back to life, he decides to journey to the netherworld himself. What awaits Masakazu there are the supernatural creatures who took away his wife, and someone else he recognizes... At last, the destiny of the desperate Isshikis will reveal itself.
