aka Durrr!
Also, hi! *waves* World of Warcraft sucked me away from the underwhelming anime series for awhile. I'm also only watching 2 series currently, OP and Durarara.
Ryuugamine Mikado is a boy who longs for the exciting life of the big city. At the invitation of his childhood friend Masaomi, he transfers to a school in Ikebukuro. Masaomi has warned him about people he doesn't want to cross in the city: a champion fighter, an informant, and a mysterious gang called "Dollars." Nervous from Masaomi's stories, Mikado witnesses an urban legend on his first day in the city, the Headless Rider astride a black motorcycle. From then on, the existence of supernatural cases and a gang called the Yellow Turbans will rise to the surface, and Ikebukuro will pushed to the breaking point.
In terms of description, that is fairly accurate, but it doesn't quite convey the sheer energy of the series. For one thing, the second episode basically was a retread of the first, but with more detail on the secondary plot introduced in the first episode and from a different viewpoint as a result.
In a way, you can tell the director was also the director to Baccano, but in a way, stating that explains a lot of the series as well. The character designer also worked on Baccano, but the original designer is the same person who created Yozakura Quartet, and it shows. The series is smooth and pleasant to watch. I also love how they did give a voice to the Headless Rider, even though it was definitely used as a helper to prevent tediousness.
So far, there are only 6 episodes out of the series and I've only seen 3, but I would definitely say to give it a watch and see what you think.
