Nine men and one woman are known as "Chikan Jyu Nin Tai" - they are famous train molesters. They make all the lustful dreams of their clients related to "chikan" come true. They surround the victim and stand in a cordon, thereby protecting the client from detection. After satisfying their lustful needs, the victim is mandatorily given 10,000 yen in compensation. In Japan, molestation is considered one of the dirtiest crimes and is punishable by up to 20 years in prison, so the people of this gang are adventurers.
