Chouchou Jiken Rhapsodic

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.
