Everybody, this girl is my younger sister. Please get along with her. I'm sorry. Because... she has a very nice scent.

"Hey, you have a really sweet smell. Fufu, when I touch you, that sweet smell gets stronger."

The 5th year of the Shouwa era (1930)... A girl descends into the blossoming Yokohama, a cosmopolitan town brimming with an exotic atmosphere.

An aesthetic mystery delivered to you by 3 companies: Aria (Kodansha), Red Entertainment and Otomate.

Your scent will drive them wild.

That look on your face... Maybe you've met "those guys" already?

Bad things will definitely happen.
