Anarchy
Anri Sonohara runs away from the Yellow Scarves. She hides in a dark alley and is scared of what will happen if Kida finds out her identity. The scene flashes back to when Anri was fetched out of the hospital by Mikado and Kida. Anri is puzzled over Kida's strange behaviour and worries about causing a gang war over Saika. This prompts her to ask her 'children' in Yellow Scarves who their leader is, not believing it when told it was Kida and decides to investigate. The scene comes back to when Celty sends her a text message and rescues her. As Celty drives away, a Yellow Scarves member throws a metal pipe at Anri, who brings out Saika and slashes it away just in time. Kida comes to the conclusion that Saika is also in Dollars. Meanwhile, Izaya fills Mikado in on the details of the gang war between Yellow Scarves and Blue Square. Kida realizes that he had only fought as the Yellow Scarves's leader for Mikajima Saki, and now his best friend Mikado.

Durarara!!
In Tokyo's downtown district of Ikebukuro, amidst many strange rumors and warnings of anonymous gangs and dangerous occupants, one urban legend stands out above the rest—the existence of a headless "Black Rider" who is said to be seen driving a jet-black motorcycle through the city streets.
Ryuugamine Mikado has always longed for the excitement of the city life, and an invitation from a childhood friend convinces him to move to Tokyo. Witnessing the Black Rider on his first day in the city, his wishes already seem to have been granted. But as supernatural events begin to occur, ordinary citizens like himself, along with Ikebukuro's most colorful inhabitants, are mixed up in the commotion breaking out in their city.
