The star of this work is Nanao no A-chan! - She is a beautiful G-cup busty beautiful girl with a smile on her girlish charm and cuteness of behavior! She doesn't have any special skills and is humble enough to say that she is looking for something, but the staff says that she can be proud of her friendliness who can get along with anyone. Such an adorable A-chan is thrilled to shoot on location in a tropical country for the first time, and everything she sees and comes into contact with is fresh and full of raw expressions. It seems that the three-day location shooting was the best, and he wants you to enjoy it, including adult-like makeup and clothes. The making-of and off-shots are also a big catch, and you can see them enjoying themselves with the staff and the office's Takashiki Rua-chan. Let's enjoy the seven changes of the innocent A-chan in the refreshing tropical cheerfulness where you can hear the sound of the waves!
