Walking on Thin Ice.Anri and Saki arrive at Shinra and Celty's apartment, where Seiji, Mika, Namie, Kyohei, Walker and Saburo are planning to save Erika after she messaged Walker that she is in trouble. Mikage continues to hold off both Vorona and Kasane, while Izaya stands safely at a distance as he pumps carbon dioxide in the filter system to suffocate Shizuo. Izaya lights a match to cause the warehouse to go up in flames, but the Celty's shadows engulf the explosion. In the online chat room, Chikage tells Mairu and Kururi that people in real life are no different than people online. During high school, Shizuo was upset that Shinra introduced him to Izaya, but Shinra mentioned that he would give up anything for the woman he loved. In the present, Shizuo breaks a steel beam that Izaya is standing on and bats him out of the area. Masaomi and Chikage go on the roof of Tokyu Hands, the downtown chain department store, as they try to figure out why a bunch of people are crowding around Russia Sushi at night. As the two see the Blue Squares from a distance, Chikage plans to go down there and take off their masks while Masaomi tells him which one is Mikado. Meanwhile, Manami unintentionally finds an injured Shinra at another apartment previously owned by Yodogiri. As Manami walks Shinra and hails a taxi, she asks him what Izaya hates more than anything else. Shinra compares Izaya to a windsock, in which accepting humanity is like emotional protection for Izaya. The things that Izaya hates the most are the ones that cause him pain, like a bad cut or having his heart broken.
