Anri has noticed a change in the city of Ikebukuro as well as the behavior of Mikado. In the online chat room, the users discuss the rumor that Ruri Hijiribe is being stalked by a member of the Dollars. Also, they mention that the Blue Squares, disguised with blue ski masks patterned as shark heads, are sweeping the city to unsubscribe members of the Dollars who mug bystanders for money. At the Rakuei Gym, the stalker is revealed to be Kisuke Adabashi, who carries a stash of photos of Ruri in his gym bag. After surviving a dangerous mission of transporting a pet snake to the home of a mogul's daughter, Celty comes back to the apartment and jumps into Shinra's arms with relief. Anri shows up and expresses her concern to them regarding Mikado's unusual behavior. Meanwhile, Shizuo is visited by Kasuka Heiwajima, who brought Ruri with him. Shizuo first mistakes that Kasuka and Ruri came by to get married. However, Kasuka says that Ruri is being stalked by a member of the Dollars who is tied with a group that deals information about idols online. Although Shizuo is unable to help them due to resigning from the Dollars, Ruri will be staying at Kasuka's place in the meantime. A flashback reveals that Aoba asked Shinra and Celty for an email address when they returned from their getaway trip. In the present, Anri reveals that Mikado has been hanging around Aoba at school. Shizuo, Kasuka and Ruri show up at Shinra and Celty's apartment. After Aoba reveals to Mikado that Ruri's stalker is a member of the Dollars, Mikado replies that the Dollars do not need those kinds of members. New users later appear in the online chat room.
