One day, she makes contact with a man claiming to have information about her friend, but he is actually a member of an exclusive, high-class rape club called [GOKAN CLUB], which secretly abducts and confines schoolgirls to orchestrate rape shows. The club operates in secrecy, trapping numerous schoolgirls in its web. Armed with this information, Yoko risks getting caught herself, but she steadily closes in on the truth in a desperate attempt to save her friend.
