Nadeko Sengoku's classmates are all strained thin due to the “hocus-pocus” of con artist Deishu Kaiki. Because of that, Nadeko goes to school every day with a heavy heart; but one day, she starts seeing white snakes all over the place.

Nadeko Sengoku is asked by Kuchinawa, a snake deity, to find his object of worship. Nadeko accepts and goes to junior high school during the day with Kuchinawa, who resembles a white scrunchie, while searching the town at night for the object of worship.

Nadeko spent the evening at the Araragi residence after Koyomi mistakes her for running away from home and takes her back to his place. The next morning, she talks to Koyomi's younger sister Tsukihi, a friend from back in grade school.

Nadeko finally found the object of worship. Kuchinawa, now in a good mood, tells Nadeko that he will grant her a wish. But Koyomi shows up right then and starts his attempt to convince Nadeko to let go of that object of worship.
