The Devil's Proof.Shisui finds herself strapped to a chair in an unknown location with her Dominator pointed towards her and one of her eyes taken by her kidnapper, Kirito Kamui. As her fear causes her Crime Coefficient to rise, Kamui uses a peculiar method to suddenly bring it back down. Meanwhile, Akane and the others investigate the message that had appeared in her apartment and find no signs of anyone having broken in, leading some to believe Akane may have done it herself. On the way back, Akane visits Jouji Saiga, who turned himself in after helping Kogami during the Makishima incident, to hear his thoughts on the case. Later, Akane speaks with Bureau Chief Joshu Kasei, who gives Division 1 authority to look into the case and tells her to be cautious of Togane. As Akane begins her investigation, her partner Mika Shimotsuki becomes distrusting of Akane's actions, arresting a man named Kotoku Masuda who claims to know Kamui. Meanwhile, Aoyanagi, who has been contacted by Shisui and told to go to a mental care facility, finds herself lured into a trap by someone who violently attacks her while still maintaining a low Crime Coefficient and also mentioning Kamui's name.
