3 cours. The second cour (Durarara!! X2 Ten) begins in Summer
while the final cour titled Durarara!! X2 Ketsu is to air in the beginning of 2016.

For a bit of recap, the series takes place in Ikebukuro where many abnormal events takes place in this seemingly normal city. The way Durarara!! X2 Shou operates involves many characters and events together that are intertwined. As such, expect the narrative and perspective of the season to follow their stories. The first few episodes reintroduces you the feel of Durarara again with the wild fun of the show. This cour covers several arcs that details various events that is immaculately engineered.

The first few episodes already sets up an arc for a wild frenzy taste when the audience is introduced to mysterious murders.memorable characters, and x2 Shou
follows suit by introducing a lot more. With the entire first arc dedicated to this, some excellent standouts emerge, most notably Mairu and Kururi Orihara, Izaya's younger twin sisters, who steal the show for their entire duration onscreen. However, while some of the new characters are excellent, the sheer excess of them is Durarara x2 Shou's biggest problem.

Once the second arc gets into full swing, we're treated to a plot built around remnant factions of the Blue Squares, a new gang called Torumaru, multiple corporations, several Yakuza factions with links to said corporations, a serial killer, a pair of Russian assassins, and a young girl with a tazer, along with all the previously established Dollars from the previous season. This arc lasts 8 episodes
