Ichiro Hanada is a hyperactive little boy who lives with his parents, sister, and grandfather in a rural town. He is always up to some kind of mischief, often teasing his sister or making rude comments to others. Consequently, his mother constantly scolds him, and even the neighbours express disturbance from time to time on how rowdy he can be. One day, after pulling a terrible prank, Ichiro sprints onto the streets as his mother chases him. He steals a nearby bicycle and takes on a dangerous route, eventually being hit by a truck. Miraculously, he survives the crash, requiring nine stitches to the back of his head and balding for the surgery. However, the near-death experience gains him the ability to see ghosts—the last thing he needs in his life. Since Ichiro is the only one who can communicate with them, several ghosts of people who have recently died come to him, seeking help to fulfill their last wishes before achieving enlightenment. Each adventure with a ghost leaves the young and curious boy with a different lesson that gradually makes him wiser.

Now that Koyomi Araragi and Hitagi Senjougahara have graduated, very few familiar faces remain at Naoetsu Private High School. One of these is Suruga Kanbaru, holder of the Monkey's Paw. When she begins to hear talk of a mysterious being known as the Devil who will magically solve any problem, Kanbaru immediately thinks these rumors are about her and decides to investigate. She discovers the Devil is actually Rouka Numachi, a former basketball rival from junior high who is no longer able to play due to a leg injury. Rouka provides free advice to those who seek her out. Acting as a collector of misfortune, she enjoys relieving the stress of her clients by providing them with the false hope of having their problems solved. Although Kanbaru sees no real harm being done, she reprimands Rouka for lying and heads home, relieved she is not the cause of the rumors. But she may have a reason to worry after all: she finds that her left hand has reverted back to its human form.

Ohana Matsumae has been working at Kissui Inn as a waitress for a while now. However, she realizes that she is starting to lose her desire to sparkle, having grown accustomed to the routines of her job. As this was a desire she had when she first moved to the inn, the realization bothers her. While having Yuina Wakura—Ohana's classmate, friend, and the daughter of rival Fukuya Inn's owner—under her as an apprentice, Ohana stumbles upon some old archives that mention her mother, Satsuki. Ohana does not know much about her mother, but these archives could shed some light on her past. Besides learning more about her mother, it is business as usual at Kissui Inn—though with a couple of challenges to test Ohana and the staff of the inn.
