Yuko's husband, Mr. M, repeatedly watches the tape that became the only clue after her disappearance. “No matter how I look at them, they don't seem like classmates,” he says. He initially watched it to identify the perpetrators, but the sight of strangers increasingly defiling his wife aroused him so intensely that his erection would not subside. Disturbed by his own fetish, he authorized the footage for a porn release and requested a public search. Yuko Okuyama of Adachi, Tokyo, has been missing since 11:30 p.m. on August 28, 2019. This footage was re-edited from material provided with her family's consent.
