The twentieth chapter to the Girls Bravo Manga Series.
Fukuyama has stolen Miharu and Koyomi's undergarments and an embarrassing photo of Kirie. In order to get them back, they must compete in a garden tournament, or else they will be part of Fukuyama's personal collection forever.
The anime episode Fight Bravo! is very loosely based on this story, except the tournament was a fighting arena and it was only Kirie's humiliating photo that needed to be recovered.
