The girls are given sleeping pills while drinking at a club, and are then raped in group sleep and sexually penetrated... Mei Miyajima

The men who had attacked Mei were guilty. They incapacitated her by planting sleeping pills in her drink and then forced her to perform sexual acts on them. Furthermore, they recorded the act and threatened her, which can only be described as despicable. As in the case of Mei in the film, it is important to be aware of the dangers involved when one engages in nighttime activities.
