Kana (Natsumi Ishibashi), who works at a factory in the town, is quiet at work, but originally has a bright personality. I had the chair (Louis Ghost) that I had wanted for a long time carried to my house and grinned while heading to the table alone. Suddenly, a strange elementary school student, Chie (Shiratori Tamaki), comes to ask me to lend a fashionable chair for a scavenger hunt. Kana reluctantly takes out her chair and walks around with her, and Kana notices a strange coincidence.
