Baccano! [AniDB]
Darker Than Black [AniDB]Baccano is Italian for noise, but Narita translates it as "stupid commotion." Each of the stories in the series involves several unrelated plots intersecting and crossing each other as events spiral farther and farther out of control. Immortal alchemists, mafia operated speakeasies, and many other elements of pulp fiction mashed together for a world straight out of the movies.
In Tokyo, an impenetrable field known as "Hell's Gate" appeared ten years ago. At the same time, psychics who wield paranormal powers at the cost of their conscience also emerged. Hei is one of the most powerful of these psychic agents, and along with his blind associate, Yin, works for one of the many rival agencies vying to unlock the mysteries of Hell's Gate.
