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.

A couple running a small cafe, Izumi (Natsumi Ishibashi) and Yuta (Aoi Nakamura). Water resistant chairs (navy chairs) developed by the US Navy are lined up in the store so that customers will not be interrupted even in the rain. The relationship between the two is twisted because the store's management has become unsuccessful.

A mysterious beauty (Haru Kuroki) dressed in red clothes comes to the bar "Human Voices" with the hired store manager Tsuyoshi Muro, who had spared time alone. Suddenly, the woman begins to read aloud modern poetry, perhaps because it is her own work, but she is confused because Tatsuzo is confused because she leaves behind saying "make it a luck".
