The Asian Tween Girls are a large group of assassins commonly hired by the Yakuza.
Whenever the army of Asian Tween Girls is required, a high ranking Yakuza official will blow the 'Asian Tween Horn' at 10:30 at night and the assassins will converge on the nearest Cheesecake Factory.
There seems to be no way to stop the army of Asian Tween Girls. However J-Pop or K-pop seems to weaken them, forcing them into a state of dance and celebration.
