Durarara!! or DRRR!! (デュラララ!!) is a light novel series written by Narita Ryohgo, also well-known for his Baccano! series, which takes place in the same world. The illustrations are done by Yasuda Suzuhito. The first series is complete at 13 volumes. However, the continuation, a second series named Durarara!!SH, is currently being published.
Many unusual people gather in Ikebukuro, Tokyo--- a youth who yearns for an un-mundane life, a hoodlum, a stalker, a young man who deals in information ‘for fun’, a black-market doctor, a guy who dresses like a bartender with inhuman strength, as well as a ‘headless rider’ riding a black bike. Durarara!! tells the abnormal stories of all of these people and more.
Power of the Verse
The verse isn't actually very strong, possessing mostly street level characters with a few wall level and Small Building level characters. There's some supernatural elements, as one of the characters is an immortal Dullahan that can manipulate shadows and some other characters have a sword than allows them to control the people they cut, but the verse is still weak in terms of raw power.
