After the most recent slasher attack against Anri's bullies, she is taken in by the police for questioning in regards to the attacks. Mikado and Masaomi find out through Izaya and rush to the police station to check on her. Anri tries to shake off the two by letting them know that she is okay, but they do not buy it and walk her home, not wanting a repeat incident to occur. Mikado laments from a comment Izaya made about the rumors behind the Slasher being a member of the Dollars as he tries to figure out the connection if there is any. At Izaya's office, it is shown that Namie is now his assistant and Shingen threatened her with a toy gun since he wanted to know about Celty's head and what Izaya has planned for it.
At Shinra's apartment, he has an accidental run in with Shingen in the shower as he assumed Celty was there, seeing his father nake scarring him. Celty arrives home as she wonders what happened as she sits down with the two. She and Shinra tell Shingen about their romance and love for one another as the mysterious doctor strongly disapproves of the whole thing. He tries to talk the two out of it, but they do not relent. After a while, Shingen spills the beans that he was the one who stole Celty's head twenty years ago with the demonic blade called Saika. Shinra realizes that the demon blade used to detach a soul from a body may be involved in the Slasher attacks.
Celty goes out for a job later in the evening and spots Mikado looking down in the park. She approaches him and sits with him, asking him whats wrong. Mikado confesses he is worried that the Slasher attacks are his fault since his gang and the attacker may be related. He confides in her that he is worried about what to do. Celty assures him its not his fault and agrees to look into it herself since he helped her out in the past with Namie. After their meeting, Celty meets with Shizuo who she asks for help in the investigation. Shizuo discovers a blood lust in his body as Celty is a good friend and hearing how she was attacked pisses him off, saying he will kill whoever the Slasher is.
In the present, Anri is finally able to shake Masaomi and Mikado as she makes her own way home the same night she was attacked. Instead of heading straight home, she instead stops at the crime scene with the blood still fresh on the pavement. As she is lost in her thoughts about everything, she fails to notice a shadowy figure approaching her from behind as it appears that the Slasher is not yet finished with Anri.
