Kotaku: Ayaman Japan is a trio of girls who love to party. There's Ayaman, the outfit's leader and "Crotch Boss" (the group also has a "Boob Boss" and an "Ass Boss"). The Boob Boss, Asami Sakurada, used to moonlight as a game event companion. Now, she emcees game launch events.
Ayaman Japan consists of idols you can *ahem*. The girls appeared at the Gears of War 3 launch event, along with male comedy duo Fujiwara and eyebrowed female comedian Masayo Miyazaki.
All the females on stage at the event were supposed to be dressed like Gears of War's Anya. The key words here are "supposed to be".
