The last prey Ryuichi chose was Tsukino Tamana. She is a neat and class representative, but she is just looking at Ryuichi who is being bullied with a frosty look. For Ryuichi, she is a woman who covers her mouth and nose with a handkerchief and looks like she is looking at dirty things. It was Ryuichi's most enduring silent violence. She was exactly the woman she deserved for her final target. Chihiro's investigation reveals that Tamana finds sexual desire in the smell of Smel Fetish, especially the semen of a man. Tamana, who couldn't control her desires because of her smell, says she is masturbating in the bathroom at the school. Ryuichi who makes Chihiro give a blowjob makes Chihiro's hand catch semen. And he instructs him to take classes without washing his hands. Responding to the smelling semen from Chihiro's hands, Tamana appeals to her teacher for her illness and begs her to go to her infirmary. However, the destination where Tamana went was the toilet.
