A year and a half after the end of the Dollars, Ikebukuro welcomes a new wind.

Yahiro Mizuchi, a cowardly boy with a knack for fighting, moves to Ikebukuro after a childhood of ostracization in his hometown in Akita. Coming to the city in hopes of meeting the famed Headless Rider and validating his existence as a 'monster," he enrolls in Raira Academy as a freshman, where he quickly befriends fellow classmates Kuon Kotonami and Himeka Tatsugami, both of whom possess their own reasons for seeking out the urban legend. Meanwhile, the rider in black has yet to be seen in the city for the past half year, and anyone who has since attempted to seek out Ikebukuro’s resident Dullahan has vanished without a trace.

With a new start on life, Yahiro wants nothing more than to live out a quiet, ordinary existence, but the city of Ikebukuro has other plans...

Name Trivia

 * The “SH” in the title is an abbreviation of “Snake Hands.” Derived from the Chinese idiom “adding legs to a snake,” it refers to the act of adding unnecessary details onto something that should otherwise be complete. It originates from a tale in which several men compete to finish a drawing of a snake as quickly as they can. The story goes that the man who completed his snake first went so far as to add legs, resulting in his ultimate defeat.
 * Durarara!! SH itself is the "snake’s legs" to Durarara!! With the original series resolved, Narita refers to the sequel as an unnecessary addition to an otherwise complete story. However, he goes on to state that were the legs of a snake to evolve into arms and further into hands, then the snake could become a dragon and thereby grow into something greater than what it was before.
 * Before the real meaning was made known, rumors began to spout that the SH in the title referred to the character Shizuo Heiwajima. Based on this, many fans speculated that the sequel may instead have been a prequel, focusing on the characters within the cast who had attended Raijin Academy and their high school days.
