Durarara!! Novel Vol. 4 (novel)

"Do you enjoy being the Black Rider who's been spotted all over Ikebukuro over the past few years now? Why is it that you're riding such a dangerous bike all over the place? Are you aware that you're violating the law?!"

Ikebukuro, Tokyo. A place full of fires waiting to be lit and plenty of people ready to light a match: Twins who are the perfect opposite of each other. An idol who's nothing like her older brother. A girl with a crush on her senior in the Dollars. And a headless rider with a bounty on her...uh, head. Keeping the peace is probably not gonna happen.
